summary: Check that snap timer services work

details: |
    A snap service may define a timer declaring when the service must
    be run automatically. Those timers translate to systemd timer
    units.

    This test verifies that the installation of a snap with timers, or
    enabling of the snap, will create corresponding systemd timer. It
    will also verify that removal or disabling of the snap will also
    remove the timer units.
