summary: Check that own services can be controlled by snapctl
details: |
Snaps should be able to control their own services via snapctl.
This test verifies that this is the case by installing a snap with multiple
services and a configure hook which allows for two capabilities:
1. Controlling one of those services via snapctl according to the command
to which the `command` configuration is set.
2. Setting another service option via snapctl according to the value of the
`service-option-source` configuration which is itself retrieved via snapctl.
The test then verifies the following:
1. After installing, the service is initially running.
2. Changing the configuration to stop, start, stop, and restart each result
in the service being controlled accordingly via snapctl.
3. When the configuration was set to restart, the restart command was
executed as part of the change associated with the configure hook.
4. The `service-option-source` configuration can be successfully retrieved
in a configure hook via snapctl and used to set another option via snapctl
as well.
5. Reinstalling the snap with the configure hook set to call
`snapctl restart` results in the snap being successfully reinstalled and
the service successfully restarted.
