Add support for redis sentinel and slaves

Browse Source 
If the correct configuration settings are set in the answer file
redis and redis-sentinel will be installed and configured on slave
and sentinel hosts. The sentinels will monitor the master and
keep track of the slaves. If the master dies, then the sentinels
will consensually establish a new master.
