Subject: [PATCH 10/15] Add request pool to improve delivery performance
 (#10353)

* Add request pool to improve delivery performance

Fix #7909

* Ensure connection is closed when exception interrupts execution

* Remove Timeout#timeout from socket connection

* Fix infinite retrial loop on HTTP::ConnectionError

* Close sockets on failure, reduce idle time to 90 seconds

* Add MAX_REQUEST_POOL_SIZE option to limit concurrent connections to the same server

* Use a shared pool size, 512 by default, to stay below open file limit

* Add some tests

* Add more tests

* Reduce MAX_IDLE_TIME from 90 to 30 seconds, reap every 30 seconds

* Use a shared pool that returns preferred connection but re-purposes other ones when needed

* Fix wrong connection being returned on subsequent calls within the same thread

* Reduce mutex calls on flushes from 2 to 1 and add test for reaping

Subject: [PATCH 11/15] When deleting & redrafting a poll, fill in closest
 expires_in (#11203)

Use the smallest preset expires_in such that the new poll would
not expire before the old one.

In the typical case of a quick delete & redraft, this results in
using the same poll duration.

Fixes #10567

prior to the switch to the nsa gem and should have been removed
at that point as it no longer does anything at all
