* Stops the daemon, blocking until any current requests/connections have been satisfied.

* <p>This is the semantically the same as sending the daemon the Stop command.
*
* <p>This method does not quite conform to the semantics of the Stoppable contract in that it
* will NOT wait for any executing builds to stop before returning. This is by design as we
* currently have no way of gracefully stopping a build process and blocking until it's done would
* not allow us to tear down the jvm like we need to. This may change in the future if we create a
* way to interrupt a build.
*
* <p>What will happen though is that the daemon will immediately disconnect from any clients and
* remove itself from the registry.
