Once we have a Watch persistent streams from workers to the controller, we can notify workers that they need to sync VMs right away upon scheduling.

Probably a worker should still poll updates every 15 seconds and the push from the controller will just reset interval.

Before we had two main loops: controller loop to assign VMs and worker loop to start VMs. Each of the loops was performed upon an interval every N seconds.

This change introduces a mechanism for reactively requesting loop execution:

 1. Controller loop will be executed upon VM creation to try to immediately schedule.
 2. A worker will be notified upon a VM assigment and worker loop will be requested to sync immediately.

 Fixes #31
