Reduce memcached memory configuration
Previously the memcached configuration was set to use the defaults which
would be 95% of the avaiable ram in the system. This can lead to memory
contention issues if memcache is heavily utilized. This change reduces
the default to 50% and exposes the ability to tune this configuration.
