Log changes to patterns

[coreymckrill]

There are probably several reasons why we'd want to be able to audit changes made to a pattern. One is so we can see who removed a pattern from the directory, when they did it, and why, if they include a reason.

A log entry should have a date, user name, type of change, and an optional comment. It might look something like this:

Date	User	Action	Comment
2021-03-30 11:05:05	matt	Submitted
2021-03-30 11:05:45	patternbot	Flagged for manual review	Possible copyright issue
2021-03-30 15:21:03	admin	Approved	Looks ok
2021-03-30 15:22:02	someotheruser	Flagged for manual review	Inappropriate content
2021-03-30 16:38:55	admin	Removed	Content is inappropriate

Log entries could be added both by automated processes (by "patternbot" or something) or by user-driven actions. In some cases the comment field could get populated automatically with pre-determined values. In other cases, like when a moderator is manually changing the status of a pattern, a textarea field should be available to add a reason, which would then get added to the log's comment field.

Planning to use the Stream plugin for logging changes, so this is pending the merge of one of these PRs:

• Frontend support added to Posts Connector. xwp/stream#1223
• Posts Connector: Enable on the front end to ensure logging happens for REST API events xwp/stream#1264
• Connectors: Check the request type and unregister connectors that don't support it xwp/stream#1269

For the "adding a reason part" work is in progress on an "Internal Notes" plugin.

Logging changes isn't critical for the initial launch, so I changed the milestone on this one to Pattern Creation instead.

Development on the Stream plugin seems stalled, I haven't gotten any further responses on my PRs. I suspect we will need to write our own connector for post changes if we still want to use the plugin.

The xwp/stream#1264 pull request has been merged and will be included in the next version of Stream.
