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. Change-Id: Ie8a48ff4cf509e93d7c1487813d5feed5e5131a4 Closes-Bug: #1662941
