Title:
  motd messaging changes regarding apt updates

Status in update-notifier package in Ubuntu:
  Fix Released
Status in update-notifier source package in Trusty:
  Fix Committed

Bug description:
  [Impact]
  Changes to wording regarding the ESM support available for Trusty. Additionally, reorder command output after UX review.

  [Test Case]
  test_motd.py has unit tests for all of the combinations of upgrade types possible. It's also possible to run "/usr/lib/update-notifier/apt-check --human-readable" on a system with ESM configured (enabled or disabled).

  [Regression Potential]
  Only strings are changing in this update and this could be considered a follow up SRU to bug 1822340 which created no issues.

  [Notice]
  This is only being SRU'ed to Ubuntu 14.04 (as with the previous SRU) as Ubuntu 16.04 and Ubuntu 18.04 will have some additional changes.
