Revert 20158:f9ce5858f7ea xend: Support "bootloader" mode for "drbd:" devices

block-drbd (provided by drbd project) handles all the details that
c/s 20158 introduces within xend.  Subtleties of configuring storage
subsystems should not be handled by xend, but instead delegated to the block
script mechansim provided by the xen toool stack.

Note:  Patch submitted upstream but not (yet) accepted since xend is on
       the way out.
