Alex Kalderimis d30a90a354 Prevent unauthorised comments on merge requests
* Prevent creating notes on inaccessible MRs

This applies the notes rules at the MR scope. Rather than adding extra
rules to the Project level policy, preventing :create_note here is
better since it only prevents creating notes on MRs.

* Prevent creating notes in inaccessible Issues

without this policy, non-team-members are allowed to comment on issues
even when the project has the private-issues policy set. This means that
without this change, users are allowed to comment on issues that they
cannot read.

* Add CHANGELOG entry
