[LRUG] [ANN] redis_failover 1.0 released

[Ryan LeCompte]

I just released the big 1.0 release of redis_failover. redis_failover is a
ZooKeeper-based automatic master/slave failover solution for Redis. Big
changes in this release include:

   - redis_failover now supports distributed monitoring among the Node
   Managers! Previously, the Node Managers were only used as a means of
   redundancy in case a particular node manager crashed. Starting with version
   1.0 of redis_failover, the Node Managers will all periodically report their
   health report/snapshots. The primary Node Manager will utilize a
   configurable "node strategy" to determine if a particular node is available
   or unavailable.
   - redis_failover now supports a configurable "failover strategy" that's
   consulted when performing a failover. Currently, a single strategy is
   provided that takes into account the average latency of the last health
   check to the redis server.
   - Improved handling of underlying ZK client connection in
   RedisFailover::NodeManager
   - Add support for passing in an existing ZK client instance to
   RedisFailover::Cient.new
   - Reduce unnecessary writes to ZK
