* remove FIXME sleep codes for Sentinel related tests
** add functions for Sentinel tests (JedisSentinelTestUtil)
*** waitForSentinelRecognizeRedisReplication
*** waitForNewPromotedMaster
*** waitForSentinelsRecognizeEachOthers
**** TODO: there're no command for sentinel to list recognized sentinel
**** sleep 5.5 sec (sentinel pings to master every 5 sec)
* set HostAndPort class to public(no longer inner) class
** reason: We cannot know pool's current master if HostAndPort class is
private inner class / HostAndPort classes are duplicated (main/test)
** make getter method and parameterized constructor
*** set fields once, get anytime
There is now a single property : redis-hosts.
This property must contain at least 2 host definitions of the form "host:port" (comma separated).
Sharding tests need 2 hosts ...
If this is not the case, the default value used is "localhost:6379,localhost:6380".
Tests that required one host are using the first definition.
