Fix test_volume_migrate_attached to retype as admin

By default, Cinder policy will allow a non-admin owner
of a volume to retype a volume. That triggers a call from
Cinder to Nova to swap the volume in the guest. The Nova
swap volume API, however, is admin-only by default. So this
test fails with default policy because Cinder gets a 403
response from Nova when trying to swap the volume on the
Nova side.

This fixes the problem by using the admin client for initiating
the retype.
