Move volume_clear option to where it's used

The `volume_clear` and `volume_clear_size` option are used in `lvm.py` so we
should move the definition there.

Correct a maybe-typo in pci_manager

it does not make sense to use 'dev' again for updating self.stale.

baremetal: Remove depenency on libvirt's fetch_image method

It's messy for virt-drivers to depend on each other, so this patch alters
baremetal to use the cross-driver fetch function, instead of the libvirt
version.

libvirt: Fix kwargs for _create_image

Rescue uses the `suffix` and `disk_images` kwargs of `_create_image`, but
passes them in as positional args. We should use explicit kwargs here to be
clear that rescue depends on both of those parameters being present.

In addition, disk mapping was being passed in as kwarg, but is actually a
positional arg, so we should pass it in as a positional arg to be clear that
it's required.

Remove libvirt legacy LVM code

The Change-Id Ib36b962971fd1f66ea9a0818e91fec59e118e686 fixed an
issue which could have caused volumes no longer being able to be
cleaned up due to it's reliance on the instance_name_template
configuration option.

There was code in place to handle both disk formats which are
the legacy format (volume name prefixed by instance name) and
the new one (volume name prefixed by instance uuid).

This commit removes the legacy format which was due to be
removed from the code.

UpgradeImpact - this removes support for really old lvm names that
could have been created in Havana clouds. That means there is a
possible failure to cleanup of lvm volumes that existed uniterupted
since Havana.

Fix swap_volumes

The attach and detach calls to cinder are better handled by cinder this
patch removes them. There is another patch against this bug to modify
cinder.

The attach call is being made against the new volume after the
migrate_volume_completion request. This means it may be done after the
new volume ID in the db has been deleted.

The detach call is being run at the end on the old ID and so may end up
detaching the migrated volume from cinder's perspective.

Ironic: save DB calls for getting flavor

The commit bceb6342994fc9d38a51a19e5b07652a5fdfd503 would read
the flavor a number of times instead of passing a flavor as a
a parameter.

This save an unnecesary DB access.
