Dreamy Jazz e7393b3cc7 Exclude boilerplate maintenance code from code coverage reports
Why:
* Maintenance scripts in core have bolierplate code that is
  added before and after the class to allow directly running
  the maintenance script.
* Running the maintenance script directly has been deprecated
  since 1.40, so this boilerplate code is only to support a now
  deprecated method of running maintenance scripts.
* This code cannot also be marked as covered, due to PHPUnit
  not recognising code coverage for files.
* Therefore, it is best to ignore this boilerplate code in code
  coverage reports as it cannot be marked as covered and also
  is for deprecated code.

What:
* Wrap the boilerplate code (requiring Maintenance.php and then
  later defining the maintenance script class and running if the
  maintenance script was called directly) with @codeCoverageIgnore
  comments.
* Some files use a different boilerplate code, however, these
  should also be marked as ignored for coverage for the same
  reason that coverage is not properly reported for files.
