rinpatch adb1b0282d ConnectionPool Worker: use monitor flush instead of checking ref
`:flush` removes the DOWN message if one had arrived, so this check
should no longer be necessary.

improvements and fixes for http requests
- fix for gun worker termination in some circumstances
- pool for http clients (ex_aws, tzdata)
- default pool timeouts for gun
- gun retries on gun_down messages
- s3 upload timeout if streaming enabled

rinpatch 45be1fe00e ConnectionPool: fix gun open errors being returned without an error tuple
When gun shuts down due to the host being unreachable, the worker
process shuts down with the same shutdown reason since they are linked.
Gun doesn't have error tuples in it's shutdown reason though, so we need
to handle it in get_conn.

Closes

rinpatch 4ce6179dc7 gun ConnectionPool: replace casts with calls
The slowdown from this is most likely immesurable, however it eliminates
possible false positives when tracking dead clients.

rinpatch 7115c5f82e ConnectionPool.Worker: do not stop with an error when there is a timeout
This produced error log messages about GenServer termination
every time the connection was not open due to a timeout.

Instead we stop with `{:shutdown, <gun_error>}` since shutting down
when the connection can't be established is normal behavior.

rinpatch a705637dcf Connection Pool: fix LRFU implementation to not actually be LRU
The numbers of the native time unit were so small the CRF was always 1,
making it an LRU. This commit switches the time to miliseconds and changes
the time delta multiplier to the one yielding mostly highest hit rates according
to the paper

rinpatch 007843b75e Add documentation for new connection pool settings and remove some
`:retry_timeout` and `:retry` got removed because reconnecting on failure is
something the new pool intentionally doesn't do.

`:max_overflow` had to go in favor of `:max_waiting`, I didn't reuse the key because
the settings are very different in their behaviour.

`:checkin_timeout` got removed in favor of `:connection_acquisition_wait`,
I didn't reuse the key because the settings are somewhat different.

I didn't do any migrations/deprecation warnings/changelog entries because
these settings were never in stable.

rinpatch 58a4f350a8 Refactor gun pooling and simplify adapter option insertion
This patch refactors gun pooling to use Elixir process registry and
simplifies adapter option insertion.

Having the pool use process registry instead of a GenServer has a number of advantages:
- Simpler code: the initial implementation adds about half the lines of code it deletes
- Concurrency: unlike a GenServer, ETS-based registry can handle multiple checkout/checkin
requests at the same time
- Precise and easy idle connection clousure: current proposal for closing idle connections in
the GenServer-based pool needs to filter through all connections once a minute and compare their
last active time with closing time. With Elixir process registry this can be done
by just using `Process.send_after`/`Process.cancel_timer` in the worker process.
- Lower memory footprint: In my tests `gun-memory-leak` branch uses about 290mb on peak load (250 connections)
and 235mb on idle (5-10 connections). Registry-based pool uses 210mb on idle and 240mb on peak load
