Add handler when systemd is used
The service handler will restart a sysV or upstart init script when present instead of a systemd service unit. In Xenial both upstart and systemd service files can be present at the same time which can create an unintended consequence by restarting the wrong service. This change creates a guard so that if systemd is used we restart using a systemctl command otherwise we use the service module. > NOTE a systemctl command is used because the systemd module is not available until ansible 2.2 Change-Id: I71cd03ac0f10e88e83c085b7a87b7b2f710d0c3e Signed-off-by: Kevin Carter <kevin.carter@rackspace.com>
