Adam Williamson 248b7a9536 revise storage: better test loading, shared disk selection ...

Summary:
This contains several tweaks to storage handling. It adds a
method for disk selection which all the storage tests can
share. It sets up a more extensible approach for main.pm to
run the storage tests, instead of an ever-growing forest of
'else' clauses. Finally it sets up a couple of methods for
changing partitioning schemes on the custom part screen and
uses one of them in the software RAID test; the other will
be used for other custom storage tests.

This kills the two_disks needle. I could keep it and work
it into select_disks, but it doesn't fit naturally and I
really just don't see the point of the needle. The only thing
we lose is we don't check that anaconda actually sees two
disks in the 'attach two disks, only install to one' test
(that's server_sata_multi), but the other multi-disk tests
will serve to catch that case failing for some reason.

What I actually intended to do was add some more tests for
different custom part storage types, but it seemed a good
idea to do some of this cleanup so that can be implemented
efficiently. I'll have followups for that.

Test Plan:
Run all tests and ensure they work exactly as
before (not just that they still pass, but that the correct
test steps are actually scheduled in each case.)
