This change extends the block device lvs attributes to allow creating
a volume which represents a thin pool, and to create volumes which are
allocated from this pool.

The block device lvm lvs `size` attribute was passed directly to
lvcreate, so using units M, G means base 2. All other block device
size values are parsed with accepted conventions of M, B being base 10
and MiB, GiB being base 2.
lvm lvs `size` attributes are now parsed the same as other size
attributes. This improves consistency and makes it practical to
calculate volume sizes to fill the partition size. This means existing
size values will now create slightly smaller volumes. Previous sizes
can be restored by changing the unit to MiB, GiB, or increasing the
value for a base 10 unit.
The impact on this change should be minimal, the only known uses of lvm
volumes (TripleO, and element block-device-efi-lvm) uses extents
percentage instead of size. The smaller sizes can always be increased
after deployment.
Requested sizes will also be rounded down to align with physical
extents (4MiB). Previously specifying a value which did not align on
4MiB would consume an extra extent which could unexpectedly consume
more than the partition size.

With the removal of Python 2.x we can remove the unittest2 compat
wrappers and switch to assertCountEqual instead of assertItemsEqual
We have been able to use them since then, because
testtools required unittest2, which still included it. With testtools
removing Python 2.7 support [3][4], we will lose support for
assertItemsEqual, so we should switch to use assertCountEqual.

This causes problems for other projects incorporating dib; we don't
have a specific need for a cap.
Fix a few issues, mostly spacing or regex matches. No functional
changes.
W503 and W504 relate to leaving artithmetic operators at the start or
end of lines, and are mutually exclusive and, due to "ignore"
overriding the defaults both get enabled. It seems everyone gets this
wrong (https://gitlab.com/pycqa/flake8/issues/466). Don't take a
position on this and ignore both.
Use double # around comments including YAML snippets using "# type: "
which now gets detected as PEP484/mypy type hints.

Currently there is a bug, that tries to detach the device from a
partition at the first try, without considering that there may be
other partitions and volumes on it. Ensure that the detach is done
properly, and add a test to ensure that this happens correctly.

A recap -- we run umount phase then cleanup phase.
Currently we register a object to do the final LVM cleanup based on
the parent PV. In light of I697bfbf042816c5ddf170bde9534cc4f0c7279ff,
I believe this should just be done in the cleanup phase. Note there
was probably additional confusion because the partition removal was
done in the cleanup phase until
I7af3c5cf66afd81a481f454b5207af552ad52a32, where is was moved into the
umount phase.
Thus it is moved into the cleanup() function and this should now run,
per the comment, after everything is unmounted in umount phase.
This also exposes that we didn't have the cleanup phase in the unit
tests (because it wasn't doing anything I guess). Add it.

As described in blockdevice.py detachment and (most) resources
release must be done in the umount phase of a block device module.
Until now these jobs were done in the lvm cleanup() phase - which
is too late - especially when using nested LVMs.
This patch moves the functionality of the cleanup() phase to the
umount() phase for the lvm module.
It includes a test case that fails without applying the provided
source code changes.

This patch removes the unneeded dd calls in the lvm block device
plugin.
After removing the underlying block device, there is the need to call
'pvscan --cache'. This is done by a dedicated LVM cleanup node which
is cleaned up after the the underlying block device.

This provides a basic LVM support to dib-block-device.
