Description

There are two scenarios for this:

1. When a service is to be terminated cleanly, there must be an option to let it finish whatever work it has started before killing it.
2. If a machine is to quickly change the type of work it is doing, services need to support suspend/resume.

The Suspend command should stop the service from receiving any more requests and then block until the current requests are finished. Resume would enable the service to accept more input requests.
