T3779: Memcached seems to be automatically cleared pretty often on moma

rSPSITE325769a99e18: webapp: Set the memory usage to the currently defined value

Summary

That will avoid flip-flop changes when puppet runs in moma. With the relative default of
5%, when puppet runs, the memcached memory configuration is updated, which restarts the
services and resets the cache (which disconnect users).

This commit settles on the current moma configuration so no disconnection should occur
when landed and applied.
