Eliminate un-necessary resource executions

[wesleung]

Every run of redis2 has a minimum of 4 resources updated un-necessarily as the values/configurations has already been set.

• execute sysctl -w "vm.overcommit_memory=1
• stop service service[redis-server]
• execute the ruby block set redis path and version
• configure service runit_service[redis_prime]
