This patch adds the capability to reclaim the name and space of
an existing btrfs subvolume and then reuse (recreate) that
subvolume. This implements a capability currently available
when using non-kickstart custon configuration installs.
This modification requires a change to the pykickstart package
which adds the --reclaim option to the btrfs command.
