The current default is 1024 however this is not sufficent for most
deployments and it will cause a lot of issues if it does hit the
limit as the server will stop responding.
The overhead for this is very low and other deployment tooling
usually sets this to 8192[1], so 4096 is even very conservative.

This change cleans up the role a little bit making it more consistent.
A new configuration file has been added which will further isolate
our services using a named cgroup; this is similar to what we already do in
our openstack services. By further isolating the service from the system
we get quite a bit more control and accountability.

Add 'become' and root 'user' options to the playbook instead of using
'ansible_become' through an inventory variable.

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.
