this is following a couple of upstream changes I noticeed while
playing with dump_templates. Upstream has completely got rid of
the 'variables' keys from all dicts, and when you run dump_
templates the output does not contain any 'variables' keys, so
it seems reasonable to ditch these entirely (I think it was some
old thing that got subsumed into 'settings'). Also, when you
run dump_templates the 'prio' values come out in JobTemplates,
not in TestSuites; if you look at load_templates there's a bit
marked "we have to migrate the prio from the TestSuite to the
JobTemplate" which does exactly what it sounds like, so it
seems a good idea to move these instead of relying on that to
always be there.
While I had to re-do all the priorities anyway I tried to clean
them up a bit. The idea is roughly this:
10 - 19: most-critical sanity tests (i.e. default_install)
20 - 29: Alpha tests
30 - 39: Beta tests
40 - 49: Final tests
50+ : Optional tests
within each group I ordered 64-bit first, UEFI second, and
32-bit last (usually just as x0 / x1 / x2).
