Allow a fixed IP to be allocated to RedisVirtualIP

The overcloud stack now contains a parameter RedisVirtualFixedIPs which will
allow people to specify the IP address they would like to be assigned as a vip
used by Redis. This will allow people full control over what IPs are used as
VIPs during a deployment.
