Default to disabling haproxy for memcached

Browse Source 
Since at least the Rocky release we have been enabling

The enable_haproxy_memcached parameter is not documented but it
can be kept as it is very light on maintenance.

Changes default value of ``enable_haproxy_memcached`` to ``no``.
Memcached has not been accessed via haproxy since at least
the Rocky release. Users depending on haproxy for memcached
for other software may want to change this back to ``yes``.
