Dispatcher Refactorings to support virtualized lava slaves without master image
The dispatcher currently assumes that deployment happens via a master image that can format and populate 'testboot' and 'testrootfs' partitions. This is not (sensibly) the way to deploy to images tested under emulation such as qemu or a fast model, nor if we switch to using a JTAG or fancy sd card multiplexer to format the sd card on the image.

Whiteboard
Meta:
Headline: The LAVA dispatcher no longer assumes that deployment is done via a master image. -> The LAVA dispatcher has been refactored to relax assumptions that would prevent adding lava support for virtualized test slaves like fast-model and qemu.
Acceptance: Master image still works, but is no longer such a deeply held assumption.
