=head2 remove_backing_lv
This method does the work wiping the data from, and then deleting the logical volume backing a DRBD resource. The return value from the C<< lvremove >> call is returned. If the C<< wipefs >> call returns non-zero, that return code is returned. If something else goes wrong, C<< 255 >> is returned.
B<< NOTE >>: This does no sanity checks! This method assumes all checks were done before this method was called!
Parameters;
=head3 backing_disk (required)
This is the full logical volume path that is to be deleted.
