Rubocop upgrade + hound messages


HoundCI has upgraded their Rubocop to the latest version, 0.42, causing
some comments by the hound to appear for new rules that we have not
disabled (as they are not available in our current rubocop version, which
is 0.39).
To solve the discrepancy I have opened a PR [1] to upgrade our version to
the latest one.

If you are a plugin maintainer that uses the rubocop version defined by
Foreman core, you may need to update your rubocop settings to correctly
handle the new cops once the core PR is merged.
