* [proxy] Propagate most errors to user
This change enables propagation of most errors to the user
(e.g. auth and connectivity errors). Some of them will be
stripped of sensitive information.
As a side effect, most occurrences of `anyhow::Error` were
replaced with concrete error types.
* [proxy] Box weighty errors
Have separate routine and http endpoint to create timeline on safekeepers. It is
not used yet, i.e. timeline is still created implicitly, but we'll change that
once infrastructure for learning which tlis are assigned to which safekeepers
will be ready, preventing accidental creation by compute.
Changes format of safekeeper control file, allowing to store set of
peers. Knowing peers provides a part of foundation for peer
recovery (calculating min horizons like truncate_lsn for WAL truncation and
commit_lsn for sync-safekeepers replacement) and proper membership change;
similarly, we don't yet use it for now.
Employing cf file version bump, extracts tenant_id and timeline_id to top level
where it is more suitable. Also adds a bunch of LSNs there and rename
truncate_lsn to more specific peer_horizon_lsn.
* Add --id argument to safekeeper setting its unique u64 id.
In preparation for storage node messaging. IDs are supposed to be monotonically
assigned by the console. In tests it is issued by ZenithEnv; at the zenith cli
level and fixtures, string name is completely replaced by integer id. Example
TOML configs are adjusted accordingly.
Sequential ids are chosen over Zid mainly because they are compact and easy to
type/remember.
* add node id to pageserver
This adds node id parameter to pageserver configuration. Also I use a
simple builder to construct pageserver config struct to avoid setting
node id to some temporary invalid value. Some of the changes in test
fixtures are needed to split init and start operations for envrionment.

When several AppendRequest's can be read from socket without blocking,
they are processed together and fsync() to segment file is only called
once. Segment file is no longer opened for every write request, now
last opened file is cached inside PhysicalStorage. New metric for WAL
flushes was added to the storage, FLUSH_WAL_SECONDS. More errors were
added to storage for non-sequential WAL writes, now write_lsn can be
moved only with calls to truncate_lsn(new_lsn).
New messages have been added to ProposerAcceptorMessage enum. They
can't be deserialized directly and now are used only for optimizing
flushes. Existing protocol wasn't changed and flush will be called for
every AppendRequest, as it was before.
Since commit fdd987c3ad, it was only used in InMemoryLayers. Let's
just "inline" the code into InMemoryLayer itself.
I originally did this as part of a bigger PR (#1267). With that PR,
one in-memory layer, and one ephemeral file, would hold page versions
belonging to multiple segments. Currently, PageVersions can only hold
versions for a single segment, so that would need to be changed.
Rather than modify PageVersions to support that, just remove it
altogether.
