contint: 100% passing puppet-lint

I have added a few dummy class comments to make puppet-lint happy:

BEFORE:

  $ cd modules/contint/
  $ puppet-lint --with-filename .
  ./manifests/packages.pp - WARNING: class not documented on line 1
  ./manifests/testswarm.pp - WARNING: class not documented on line 1
  ./manifests/tmpfs.pp - WARNING: class not documented on line 1
  $

AFTER:

  $ cd modules/contint/
  $ puppet-lint --with-filename .
  $

\O/
