service stuck in agent-state pending cannot be terminated

[David Lawson]

With juju1.14.1-precise-amd64 if a service agent is stuck in the pending state, for example due to an error in installing the charm, that service is essentially unkillable. The service agent clearly appears to know it should be dying but never actually gets to the point where it can die.
