Implement the general note/comment app feature in Inventory (instance, holdings, item and container record)

Purpose: Implement Notes/Comments which is a helper app that integrates with other apps (e.g. Users, Requests) and allows users to participate in running commentary on records. You can create comments, reply to comments, tag others in comments etc.
Need to label these so it is clear that these are not bibliographic notes & they will not be blocked for editing when there is underlying MARC.

While a basic implementation of Notes has already been developed, there is more work to be done to make it functional. There are bugs (e.g. you cannot currently edit or delete notes), and incomplete features. Basic tagging of users is in place, but it offers all users, not just FOLIO operators. And the in-folio Notifications feature where one can view their alerts (namely, have I been tagged in a Note) is extremely rudimentary.

NOTE:
This story is not about the implementation of bibliographic notes. These notes are covered by UXPROD-1121
