  dm-snapshot should be in the installer environment

Bug description:
  When using snapshots there is one special situation when using
  "lvconvert --merge" on a snapshot when its origin is still in use (the
  merge subcommand is in lvconvert since Precise/12.04 at least). In
  that case the merge request is noted in the meta-data and it will get
  done the next time the volume group gets activated.

  One case where this should be supported as well would be the rescue
  environment we offer on server images. For this the dm-snapshot module
  needs to get listed in the d-i lists (Actually there could the the
  theoretical situation where someone had initiated a merge and the next
  thing done is an install into the same volume group).

  SRU Justification:

  Impact: Without this, the installer and rescue environment will
  produce an error and hide the origin to be merged (as well as the
  snapshot) making it impossible to access the origin.

  Fix: Just an additional module for the d-i.

  Testcase: Initiate a merge on a mounted origin. Then boot into the
  rescue system and try to activate the VG.
