lvm2 for a while already optimizes 'vgremove' operation to
a single commit when possible if all LVs can be
easily deactivated.
So the number of LVs doesn't matter much - but the tested
case 'test_delete_non_complete_job' seems to be taking
some time anyway to capture the exception.
So just reducing the running time of the test significatanly
as we don't need to create 64LVs for 4 'execution mode' runs.
Reduce #lv and intervals.
We are trying to ensure that the daemon stops while it's busy processing
its internal queues. Decrease the number of LVs and intervals to allow
this test to complete in less time.
During vdo testing with smaller block devices the test needs to determine
which PVs in a VG are unused. This was leveraging LvCommon.Devices, but
that isn't populated when a LV is resides on a LV pool instead of a PV.
This is a known limitation of the code at this time. For now we will walk
all the PVs in the VG looking for ones that don't have any associated LVs
and use them instead.

Previously we were injecting a missing key in the lv, vg, and pv.
Given the order of processing in lvmdbusd, this prevented us from
exercising all the error paths. Change to returning just 1 instead.
Place the addCleanup at the end as we don't want to go through clean up
if we don't make it through setUp. If we don't do this we can remove VGs
that we didn't create in the unit test.
We put this in to test one of the paths in the damon, but unfortunately
if we hit the race condition where the job actually is done we will try
to call j.Wait(1) after the remove. This fails with:
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod:
Method "Wait" with signature "i" on interface "com.redhat.lvmdbus1.Job"
doesn't exist
Which is caused by the dbus object no longer existing. We could handle
this, but the issue is we no longer have the ability to get the result to
return, they have been lost.
A better solution would be to write a specific unit test to force this code
path and handle all the possible outcomes.
