Updates minion.restart to use service.restart if system uses systemd or is a Windows system. Existing methods don't work if salt-minion is managed by the Windows service manager or systemd. This adds functionality to check for those and use service.restart if so.
Adds options to enable use of systemd or windows service to restart the salt minion. Both options default to True as we should prefer to use the service managers, but give the option to disable where users are doing something unusual like running another service supervisor.
Adds unit tests for the minion.restart function to test existing and new functionality. Also adds tests for helper functions.

What does this PR do?
Adds support to
minion.restartto detect if the minion is running under systemd or the Windows service manager. If so, it will useservice.restartto restart the minion rather than killing and attempting to restart it.If
minion_restart_commandis set it will follow the old behaviour and use that command to handle the restart.If
minion_restart_commandisn't set and systemd/windows aren't detected, preserves the old behaviour of looking atsys.argvand either just killing the minion process or killing it and attempting to restart the process with the same args if-d(for daemon mode) is insys.argv. Whilst I can see that the former option may be useful if running the minion under another process supervisor, I'm not really sure how the killing and starting the a new process could ever work... I've left it in for the moment, but it should maybe be removed in 3008.What issues does this PR fix or reference?
