Addresses the 1.82 beta clippy lint `too_long_first_doc_paragraph` by
adding newlines to the first sentence if it is short enough, and making
a short first sentence if there is the need.
This reverts #8076 - which was already reverted from the release branch
since forever (it would have been a breaking change to release for all
users who currently set TimeZone options). It's causing conflicts now so
we should revert it here as well.
## Problem
Fixes https://github.com/neondatabase/neon/issues/1287
## Summary of changes
tokio-postgres now supports arbitrary server params through the
`param(key, value)` method. Some keys are special so we explicitly
filter them out.
The list timeline API gives something like
`"wal_source_connstr":"PgConnectionConfig { host:
Domain(\"safekeeper-5.us-east-2.aws.neon.build\"), port: 6500, password:
Some(REDACTED-STRING) }"`, which is weird. This pull request makes it
somehow like a connection string. This field is not used at least in the
neon database, so I assume no one is reading or parsing it.

This PR moves the control plane's spread-all-over-the-place client for
the pageserver management API into a separate module within the
pageserver crate.
I need that client to be async in my benchmarking work, so, this PR
switches to the async version of `reqwest`.
That is also the right direction generally IMO.
The switch to async in turn mandated converting most of the
`control_plane/` code to async.
Note that some of the client methods should be taking `TenantShardId`
instead of `TenantId`, but, none of the callers seem to be
sharding-aware.
Leaving that for another time:

Downsides are:
* We store all components of the config separately. `Url` stores them inside a single
`String` and a bunch of ints which point to different parts of the URL, which is
probably more efficient.
* It is now impossible to pass arbitrary connection strings to the configuration file,
one has to support all components explicitly. However, we never supported anything
except for `host:port` anyway.
Upsides are:
* This significantly restricts the space of possible connection strings, some of which
may be either invalid or unsupported. E.g. Postgres' connection strings may include
a bunch of parameters as query (e.g. `connect_timeout=`, `options=`). These are nether
validated by the current implementation, nor passed to the postgres client library,
Hence, storing separate fields expresses the intention better.
* The same connection configuration may be represented as a URL in multiple ways
(e.g. either `password=` in the query part or a standard URL password).
Now we have a single canonical way.
* Escaping is provided for `options=`.
Other possibilities considered:
* `newtype` with a `String` inside and some validation on creation.
This is more efficient, but harder to log for two reasons:
* Passwords should never end up in logs, so we have to somehow
* Escaped `options=` are harder to read, especially if URL-encoded,
and we use `options=` a lot.
