2ce5d8137d Separate permission checks for Pageserver and Safekeeper 
There will be different scopes for those two, so authorization code should be different.

The `check_permission` function is now not in the shared library. Its implementation
is very similar to the one which will be added for Safekeeper. In fact, we may reuse
the same existing root-like 'PageServerApi' scope, but I would prefer to have separate
root-like scopes for services.

Also, generate_management_token in tests is generate_pageserver_token now.

2d42f84389 Add storage_broker binary. 
Which ought to replace etcd. This patch only adds the binary and adjusts
Dockerfile to include it; subsequent ones will add deploy of helm chart and the
actual replacement.

It is a simple and fast pub-sub message bus. In this patch only safekeeper
message is supported, but others can be easily added.

Compilation now requires protoc to be installed. Installing protobuf-compiler
package is fine for Debian/Ubuntu.

cf68963b18 Add initial tenant sizing model and a http route to query it (#2714) 
Tenant size information is gathered by using existing parts of
`Tenant::gc_iteration` which are now separated as
`Tenant::refresh_gc_info`. `Tenant::refresh_gc_info` collects branch
points, and invokes `Timeline::update_gc_info`; nothing was supposed to
be changed there. The gathered branch points (through Timeline's
`GcInfo::retain_lsns`), `GcInfo::horizon_cutoff`, and
`GcInfo::pitr_cutoff` are used to build up a Vec of updates fed into the
`libs/tenant_size_model` to calculate the history size.

The gathered information is now exposed using `GET
/v1/tenant/{tenant_id}/size`, which which will respond with the actual
calculated size. Initially the idea was to have this delivered as tenant
background task and exported via metric, but it might be too
computationally expensive to run it periodically as we don't yet know if
the returned values are any good.

Adds one new metric:
- pageserver_storage_operations_seconds with label `logical_size`
    - separating from original `init_logical_size`

Adds a pageserver wide configuration variable:
- `concurrent_tenant_size_logical_size_queries` with default 1

This leaves a lot of TODO's, tracked on issue #2748.

7480a0338a Determine safekeeper for offloading WAL without etcd election API. 
This API is rather pointless, as sane choice anyway requires knowledge of peers
status and leaders lifetime in any case can intersect, which is fine for us --
so manual elections are straightforward. Here, we deterministically choose among
the reasonably caught up safekeepers, shifting by timeline id to spread the
load.

306a47c4fa Use uninit mark files during timeline init for atomic creation (#2489) 
Part of https://github.com/neondatabase/neon/pull/2239

Regular, from scratch, timeline creation involves initdb to be run in a separate directory, data from this directory to be imported into pageserver and, finally, timeline-related background tasks to start.

This PR ensures we don't leave behind any directories that are not marked as temporary and that pageserver removes such directories on restart, allowing timeline creation to be retried with the same IDs, if needed.

It would be good to later rewrite the logic to use a temporary directory, similar what tenant creation does.
Yet currently it's harder than this change, so not done.

This shows the interaction for three get_page_at_lsn requests. For
each request, the pageserver performs three recvfrom syscalls to read
the incoming request from the socket. After this patch, those recvfrom
calls are gone:

In this test, the compute sends a batch of prefetch requests, and they
are read from the socket in one syscall. That syscall was not captured
by the strace snippet above, but there are much fewer of them than
before.

9fe4548e13 Reimplement explicit timeline creation on safekeepers. 
With the ability to pass commit_lsn. This allows to perform project WAL recovery
through different (from the original) set of safekeepers (or under different
ttid) by
1) moving WAL files to s3 under proper ttid;
2) explicitly creating timeline on safekeepers, setting commit_lsn to the
latest point;
3) putting the lastest .parital file to the timeline directory on safekeepers, if
desired.

Extend test_s3_wal_replay to exersise this behaviour.

Also extends timeline_status endpoint to return postgres information.

f25dd75be9 Fix deadlock in safekeeper metrics (#2566) 
We had a problem where almost all of the threads were waiting on a futex syscall. More specifically:
- `/metrics` handler was inside `TimelineCollector::collect()`, waiting on a mutex for a single Timeline
- This exact timeline was inside `control_file::FileStorage::persist()`, waiting on a mutex for Lazy initialization of `PERSIST_CONTROL_FILE_SECONDS`
- `PERSIST_CONTROL_FILE_SECONDS: Lazy<Histogram>` was blocked on `prometheus::register`
- `prometheus::register` calls `DEFAULT_REGISTRY.write().register()` to take a write lock on Registry and add a new metric
- `DEFAULT_REGISTRY` lock was already taken inside `DEFAULT_REGISTRY.gather()`, which was called by `/metrics` handler to collect all metrics

This commit creates another Registry with a separate lock, to avoid deadlock in a case where `TimelineCollector` triggers registration of new metrics inside default registry.

6f949e1556 Improve pageserver/safekeepeer HTTP API errors (#2461) 
Part of the general work on improving pageserver logs.

Brief summary of changes:

* Remove `ApiError::from_err`
* Remove `impl From<anyhow::Error> for ApiError`
* Convert `ApiError::{BadRequest, NotFound}` to use `anyhow::Error`
  * Note: `NotFound` has more verbose formatting because it's more
    likely to have useful information for the receiving "user"
* Explicitly convert from `tokio::task::JoinError`s into
  `InternalServerError`s where appropriate

Also note: many of the places where errors were implicitly converted to
500s have now been updated to return a more appropriate error. Some
places where it's not yet possible to distinguish the error types have
been left as 500s.

40c845e57d Switch to async for all concurrency in the pageserver. 
Instead of spawning helper threads, we now use Tokio tasks. There
are multiple Tokio runtimes, for different kinds of tasks. One for
serving libpq client connections, another for background operations
like GC and compaction, and so on. That's not strictly required, we
could use just one runtime, but with this you can still get an
overview of what's happening with "top -H".

There's one subtle behavior in how TenantState is updated. Before this
patch, if you deleted all timelines from a tenant, its GC and
compaction loops were stopped, and the tenant went back to Idle
state. We no longer do that. The empty tenant stays Active. The
changes to test_tenant_tasks.py are related to that.

There's still plenty of synchronous code and blocking. For example, we
still use blocking std::io functions for all file I/O, and the
communication with WAL redo processes is still uses low-level unix
poll(). We might want to rewrite those later, but this will do for
now. The model is that local file I/O is considered to be fast enough
that blocking - and preventing other tasks running in the same thread -
is acceptable.

bfa1d91612 Introduce RCU, and use it to protect latest_gc_cutoff_lsn. 
`latest_gc_cutoff_lsn` tracks the cutoff point where GC has been
performed. Anything older than the cutoff might already have been GC'd
away, and cannot be queried by get_page_at_lsn requests. It's
protected by an RWLock. Whenever a get_page_at_lsn requests comes in,
it first grabs the lock and reads the current `latest_gc_cutoff`, and
holds the lock it until the request has been served. The lock ensures
that GC doesn't start concurrently and remove page versions that we
still need to satisfy the request.

With the lock, get_page_at_lsn request could potentially be blocked
for a long time.  GC only holds the lock in exclusive mode for a short
duration, but depending on how whether the RWLock is "fair", a read
request might be queued behind the GC's exclusive request, which in
turn might be queued behind a long-running read operation, like a
basebackup. If the lock implementation is not fair, i.e. if a reader
can always jump the queue if the lock is already held in read mode,
then another problem arises: GC might be starved if a constant stream
of GetPage requests comes in.

To avoid the long wait or starvation, introduce a Read-Copy-Update
mechanism to replace the lock on `latest_gc_cutoff_lsn`. With the RCU,
reader can always read the latest value without blocking (except for a
very short duration if the lock protecting the RCU is contended;
that's comparable to a spinlock). And a writer can always write a new
value without waiting for readers to finish using the old value. The
old readers will continue to see the old value through their guard
object, while new readers will see the new value.

This is purely theoretical ATM, we don't have any reports of either
starvation or blocking behind GC happening in practice. But it's
simple to fix, so let's nip that problem in the bud.

5f4ccae5c5 [proxy] Add the password hack authentication flow (#2095) 
[proxy] Add the `password hack` authentication flow

This lets us authenticate users which can use neither
SNI (due to old libpq) nor connection string `options`
(due to restrictions in other client libraries).

Note: `PasswordHack` will accept passwords which are not
encoded in base64 via the "password" field. The assumption
is that most user passwords will be valid utf-8 strings,
and the rest may still be passed via "password_".

54b75248ff s3 WAL offloading staging review. 
- Uncomment accidently `self.keep_alive.abort()` commented line, due to this
  task never finished, which blocked launcher.
- Mess up with initialization one more time, to fix offloader trying to back up
  segment 0. Now we initialize all required LSNs in handle_elected,
  where we learn start LSN for the first time.
- Fix blind attempt to provide safekeeper service file with remote storage
  params.

0e1bd57c53 Add WAL offloading to s3 on safekeepers. 
Separate task is launched for each timeline and stopped when timeline doesn't
need offloading. Decision who offloads is done through etcd leader election;
currently there is no pre condition for participating, that's a TODO.

neon_local and tests infrastructure for remote storage in safekeepers added,
along with the test itself.

ref #1009
