Before this patch, GC would call PersistentLayer::delete()
on every GC'ed layer.
RemoteLayer::delete() returned Ok(()) unconditionally.
GC would then proceed by decrementing the resident size metric,
even though the layer is a RemoteLayer.
This patch makes the following changes:
- Rename PersistentLayer::delete() to delete_resident_layer_file().
That name is unambiguous.
- Make RemoteLayer::delete_resident_layer_file return an Err().
We would have uncovered this bug if we had done that from the start.
- Change GC / Timeline::delete_historic_layer check whether
the layer is remote or not, and only call delete_resident_layer_file()
if it's not remote. This brings us in line with how eviction does it.
- Add a regression test.

Without this change, when actually setting this conf opt, the tenant
would become Broken next time we load it.
Why?
The serde_toml representation that persist_tenant_conf would write out
would be a TOML inline table of `secs` and `nsecs`.
But our hand-rolled TenantConf parser expects a TOML string.
I checked that all other `Duration` values in TenantConfOpt
use the humantime serialization.
Issues like this would likely be systematically prevent by

The version of PostgreSQL that we use is updated to 14.7 for PostgreSQL
14 and 15.2 for PostgreSQL 15.
```
We started rather frequently scrap some apis for metadata. This includes
layer eviction tester, I believe console does that too.
It should eliminate these logs:

This is yet another attempt to address problem with storage size
ballooning #2948
Previous PR #3348 tries to address this problem by maintaining list of
holes for each layer.
The problem with this approach is that we have to load all layer on
pageserver start.
Lazy loading of layers is not possible any more.
This PR tries to collect information of N largest holes on compaction
time and exclude this holes from produced layers.
It can cause generation of larger number of layers (up to 2 times) and
producing small layers.
But it requires minimal changes in code and doesn't affect storage
format.

## Describe your changes
When we deploy the proxy with the default Recreate strategy, there's
always some downtime and existing connections will be shut down. Change
the strategy to RollingUpdate and delay the kill signal by one week. AWS
Network Loadbalancer keeps the existing connections alive for as long as
the pods are alive, but will direct new connections to new pods.

previously we applied the ratelimiting only up to receiving the headers
from s3, or somewhere near it. the commit adds an adapter which carries
the permit until the AsyncRead has been disposed.
fixes#3662.
Calculation of logical size is now async because of layer downloads, so
we shouldn't use spawn_blocking for it. Use of `spawn_blocking`
exhausted resources which are needed by `tokio::io::copy` when copying
from a stream to a file which lead to deadlock.
Fixes: #3657
these are happening in tests because of #3655 but they sure took some
time to appear.
makes the `Compaction failed, retrying in 2s: Cannot run compaction
iteration on inactive tenant` into a globally allowed error, because it
has been seen failing on different test cases.

Layer for building pg extensions written on Rust
It required forking:
* `cargo-pgx` (in order not to catch an ABI mismatch error (`cargo-pgx`
hardcoded ABI tcdi/pgx#1032)
* `pg_jsonschema` (to use forked `cargo-pgx` version)
* `pgx-contrib-spiext` (to use forked `cargo-pgx`)
* `pg_graphql` (to use forked `cargo-pgx` and `pgx-contrib-spiext`
version)
Before the patch:
```
postgres=# create extension pg_jsonschema;
2023-02-02 17:45:23.120 UTC [35] ERROR: incompatible library "/usr/local/lib/pg_jsonschema.so": ABI mismatch
2023-02-02 17:45:23.120 UTC [35] DETAIL: Server has ABI "Neon Postgres", library has "PostgreSQL".

ERROR: incompatible library "/usr/local/lib/pg_jsonschema.so": ABI mismatch
DETAIL: Server has ABI "Neon Postgres", library has "PostgreSQL".
```
After
```
postgres=# create extension pg_jsonschema;
CREATE EXTENSION
postgres=# select json_matches_schema('{"type": "object"}', '{}');

`pg_jsonschema` extension will be available for our customers
Enables tracing panic hook in addition to pageserver introduced in
#3475:
- proxy
- safekeeper
- storage_broker
For proxy, a drop guard which resets the original std panic hook was
added on the first commit. Other binaries don't need it so they never
reset anything by `disarm`ing the drop guard.
The aim of the change is to make sure all panics a) have span
information b) are logged similar to other messages, not interleaved
with other messages as happens right now. Interleaving happens right now
because std prints panics to stderr, and other logging happens in
stdout. If this was handled gracefully by some utility, the log message
splitter would treat panics as belonging to the previous message because
it expects a message to start with a timestamp.

Since the current default gc period is set to 1 hour, whenever there is
an immediate need to reduce PITR and run gc, the user has to wait 1 hour
for PITR change to take effect
By enabling this API the user can configure PITR and immediately call
the do_gc API to trigger gc
