Set PrivateDevices=false for MemcacheD

Browse Source 
This patch sets the `memcached_disable_privatedevices` variable in the
memcached_server role. If memcached is deployed with a container, the
PrivateDevices configuration will be disabled in the systemd unit file.

OpenStack-Ansible sets a new variable, `memcached_disable_privatedevices`,
that controls whether the `PrivateDevices` configuration in MemcacheD's
systemd unit file is enabled.
If the `memcached_server` role is deployed on a bare metal host, the
default is maintained (`PrivateDevices=true`). If the role is deployed
within a container, the `PrivateDevices` configuration is set to `true`
to work around a systemd bug with a bind mounted `/dev/ptmx`.
See `Launchpad Bug 1697531 <https://bugs.launchpad.net/openstack-ansible/+bug/1697531>`_
for more details.
