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.
