Bug description:
  [Impact]

  ubuntu-distro-info is an important source of information about the
  current support state of the various Ubuntu releases. Currently,
  however, it provides no information about the status of Extended
  Security Maintenance for Ubuntu releases, which is an important aspect
  of Ubuntu "support".

  [Test Case]

  1. Run ubuntu-distro-info --help and observer there is no mention of
  ESM

  With the version from -proposed there will be a switch to filter on
  ESM supported releases e.g. 'ubuntu-distro-info --supported-esm' and
  it'll be possible to show the number of days until the end of ESM
  ('ubuntu-distro-info --days=eol-esm --supported-esm -f). So the test
  case is really to make sure that those new filters work.

  [Regression Potential]

  If the relationship between the packages isn't right then they will
  not be upgraded together and we could end up in a situation where
  distro-info is unusable because it doesn't recognize the number of
  columns in ubuntu.csv. So try and only upgrade distro-info-data and if
  that works then there will be a regression which is bad!

  [Other Info]

  If we already had concrete ESM information in this package, it could
  have served to clear up the recent confusion about bionic's "10 years
  of support".
