Add a very simple timeout test which submits a single job and verifies
that the timeout handling will run if the backend failed to complete the
job in time.

Implement a mock scheduler backend and add some basic test to exercise the
core scheduler code paths.
Mock backend (kind of like a very simple mock GPU) can either process jobs
by tests manually advancing the "timeline" job at a time, or alternatively
jobs can be configured with a time duration in which case they get
completed asynchronously from the unit test code.
Core scheduler classes are subclassed to support this mock implementation.
The tests added are just a few simple submission patterns.
