Merge branch 'develop' into bugfix/ntp-installation-priority
Flush handlers to force them to run

Handlers for ntp help update the time, and forcing the handlers to run
ensures that the time will be in sync for the next stages.
Added notify for handler to act on

Handler should fire up ntp after installation, ensuring that it is
running and the time is being updated.
Merged handler into main file

Handler was not really needed, and so its functions moved into the main
tasks file for simplicity and clairty.
