Refactor _run_instance() to unify control flow
_run_instance() had multiple points where various classes of errors
were handled. This patch classifies the possible error/exit conditions
into the following categories:
* success
* rescheduled - an error occurred, but the build will be returned to
scheduled for another attempt.
* aborted - build was aborted for a non-error. (e.x. instace was
deleted during spawn)
* fatal - general case of uncaught exceptions resulting in the instance
going to error.
