Imported using git-ubuntu import.

Changelog parent: 7782a87448

New changelog entries:
  * Attempt to build Ubuntu image using metapackages instead of tasks; this
    is necessary in order to build a test image out of wily-proposed for the
    g++5 transition, but may be reverted later if this doesn't turn out to
    be maintainable.  (Code taken from the trusty HWE LTS branch of
    livecd-rootfs.)
