Remove Trusty support from galera_server role

NB There was an issue with https://review.openstack.org/#/c/395932/
which meant that "pid1_name != systemd" got changed to
"ansible_service_mgr == systemd" - since we are removing trusty this
task has been removed, but a fix for Newton will be made.

Change-Id: I2f502737e2cc52678cf479de2ef94b818e253622
Implements: blueprint trusty-removal
