AR::ConPool - remove synchronization around connection cache.
Renamed `@reserved_connections` -> `@thread_cached_conns`. New name
clearly conveys the purpose of the cache, which is to speed-up
`#connection` method.
The new `@thread_cached_conns` now also uses `Thread` objects as keys
(instead of previously `Thread.current.object_id`).
Since there is no longer any synchronization around
`@thread_cached_conns`, `disconnect!` and `clear_reloadable_connections!`
methods now pre-emptively obtain ownership (via `checkout`) of all
existing connections, before modifying internal data structures.
A private method `release` has been renamed `thread_conn_uncache` to
clear-up its purpose.
Fixed some brittle `thread.status == "sleep"` tests (threads can go
into sleep even without locks).
