This is part two of a two part series that refactors the exit logic
of jobs.
This series forces all jobs to use the "finalize" semantics that were
introduced previously, but only exposed via the backup jobs.
Patches 1-3 add plumbing for the auto-dismiss and auto-finalize flags
but do not expose these via QAPI/QMP.
Patches 4-7 refactor the .exit() callbacks into the component pieces
of .prepare(), .commit(), .abort() and .clean(). Except mirror, which
I cheat with.
Patches 8-10 remove the last usages of .exit in a test.
Patche 11 removes the .exit callback and the machinery to invoke it.
Patches 12-14 expose the new QMP options to all of the jobs.
Patch 15 is a doc fixup.

000: Fixed my cover letter subject. Phew!
004: Adjusted comment, added R-B
005: New; based on discussions from what is now 006 (was 005)
