This commit updates the memcached_server role to work on Trusty,
Xenial, and CentOS 7.
NOTES:
1. This role no longer creates the memcache user since both Ubuntu and
CentOS already install a suitable user
2. We have temporarily disabled testing of the log file since CentOS and
Xenial do not log to file
3. On Ubuntu we drop ulimits into /etc/defaults/memcached, we need to
figure out how to do the equivalent on CentOS
4. We update tasks/memcached_config.yml to use the correct memcached
user in limits.conf, however neither these limits or the ones in
templates/memcached.debian.j2 actually seem to be taking effect.
More work in an additional review will need to be done to clean this
all up.
Implements: blueprint multi-platform-host
