[PATCH v3 07/10] models: add addressed field and change edit permissions for comments

[Raxel Gutierrez]

Currently, there is no state or status associated with patch comments.
In particular, knowing whether a comment on a patch is addressed or not
is useful for transparency and accountability in the patch review and
contribution process. This patch is backend setup for tracking the state
of patch comments.

Add `addressed` boolean field to PatchComment to be able to distinguish
between unaddressed and addressed comments in the patch-detail page.
Change PatchComment edit permissions to match that of the patch
associated with the comment (i.e. patch author, project maintainers, and
delegate) and add permissions to change `addressed` status for comment
authors as well.
