Redis fails to start on controllers

[Sagi (Sergey) Shnaidman]

Redis fails to start on controllers in all TripleO jobs. This breaks ceilometer and gnocchi, making them to overload logs with reconnection tries and make logs huge size.

This has been caused by a recent redis update in the dependency repo to 3.2.7-1 [1], which misses the fixes from version 3.2.4-2 [2], namely:

- Install tmpfiles and /run/redis for legacy configurations

We need an updated redis package with the fix.

Was updated to redis-3.2.8-1.el7.x86_64 and started to work.
