phpredis 5.2.0RC1

This release contains initial support for Redis Sentinel as well as many
smaller bug fixes and improvements.  It is especially of interest if you
use persistent connections, as we've added logic to make sure they are in
a good state when retreving them from the pool.

IMPORTANT: Sentinel support is considered experimental and the API
           will likely change based on user feedback.
