Title: Check for stale persistent connections

Currently, php-yrmcds does not check if a persistent connection is usable or not
when an application fetches an existing connection. Broken connections are
dropped at the end of a request.

As this was an intentional design choice for maximum performance, it is handy
if we have an option to test an existing persistent connection before use.
