[FR] Log and display change history of parts

• I checked and didn't find a similar feature request

Problem statement

Have a change history for parts with at least date, user and subject to change. Currently it is not possible to track what modifications have been made to a part.

Suggested solution

If a part is created from within the admin tool, the change history can be accessed in the admin tool as shown in the image. This is stored in the django_admin_log table.

If a part is created outside of the admin tool, there will be no change history and in the admin tool it displays This object doesn’t have a change history. It probably wasn’t added via this admin site.

A change history should be stored for any part, regardless of where it's created, and (possibly in a second step) displayed on the part page. The widget shown in this image looks like it's meant to display that data.

Describe alternatives you've considered

Revision feature might be used to keep track of changes by creating a new revision for each change. This is not suitable to us because it's much less transparent and change history is not logged.

  This feature is quite important for our use case if we go for Inventree, therefore happy to jump in - some guidance would be needed.

A general "history tracking" system would be a good idea (and has been discussed at length previously) - but difficult to implement!

One potential approach would be to use django-simple-history which seems like it would be a good fit here.

The "admin history" only logs changes made via the admin site and is not as useful here.
