[Bug 1768620] Re: removal_blacklist.cfg updates

[Brian Murray]

** Description changed:

  [Impact]
  The release-upgrader tarball includes a file, removal_blacklist.cfg, which lists packages which should never be removed. During the development of Ubuntu 18.04 this list was not updated and some packages which could be removed still exist in that file which could prevent the upgrader from calculating the upgrade. This would cause a bad experience for users as they will be stuck on the previous release of Ubuntu.
  
  [Test Case]
+ Testing the release upgrade process from 16.04 to 18.04 and 17.10 to 18.04 should be sufficient to ensure that the release upgrade process works.
  
  [Regression Potential]
+ Syntax errors in removal_blacklist.cfg may cause the release upgrader crash so keep an eye out for those although it is just line removals.
