Package and Enable Memcached on Controllers/AIO 

Add memcached as a service on controllers/AIOs.

Memcached engineering values:
1. MAXCONN (-c option) : max simultaneous connections.
   Set to puppet-memcached default value 8192.
2. CACHESIZE (-m option): MB memory max to use for object storage.
   Set to roughly 10% of 8192 = 782.
3. -t option: number of threads.
   Set to number of CPU cores.

Puppet creates memcached service as 'disabled' and 'running'.
This change make sure memcached service is enabled.
