Code review comment for ~adobrawy/cloud-init:swap-linux

Thanks again for the branch! So that it is temporarily off our radar until you would like us to re-review it, I'm going to update this branch as 'Work in progress'.

Please set this branch Status back to 'Needs review' at the top when the following is addressed:
  - unit test(s) in tests/unittests/test_handler/test_handler_mounts.py
  - a comment to the affect that you have been able to sign the CLA

Again thank you for this contribution. we look forward to pulling it into cloud-init.
