* increase sentinel instance to test JedisSentinelTest
** clear() called, slave promoted to master (slave of no one), New
Sentinel force to restore it (demote) -> slave is not reusable
* ipv6 applied at Redis 2.8 -> localhost / 127.0.0.1 / ::1 is now all same
* Makefile: sleep some time for launch each sentinel (workaround to sentinel's issue)
** issue to sentinel leader vote: https://github.com/antirez/redis/issues/1419
*** sentinel may confused to vote with sentinels launched approximately same time
* Now Pool.initPool() call closeInternalPool(), instead of destroy()
** calling destroy() in Pool.initPool() may have side effect, and JedisSentinelPool did
* modify unit test to test failover twice (needs +1 slave)
** modify configurations for additional slave
raising down-after-milliseconds of sentinel 1 to avoid taking the master down and up all the time.
change sleep to 10 seconds after doing a "salveof" to avoid false negatives.
This test will set up and get a master from a Redis master slave pair being
watched by 2 Sentinels. It pings the master, segfaults it, asks the pool for
another connection and makes sure it can ping it.
This commit also restores the pom.xml file's scm information back to
xetorthio and adds the default Sentinel port to the Procotol.
