Refactor history to be Tenancy object

[jon-nfc]

The history model is not a tenancy object. due to this there is no filtering by organization can be done.

Details

Adjust the history model so that it is a tenancy model. The model only requires that it contain an organization field.

This cant be done by simply importing the TenancyObject abstract class, as this class also includes the history saving feature. Thought will need to be placed into how this will be done so as not to create a recursive loop.

Migration

This change will require a migration in addition to the migration to add the field. The migration will need to conduct the following in order so as to change the model to be a Tenancy Model:

• add the organization field with type int
• iterate over the entire history table fetching the history entry item using item_class if parent_class does not exist
• with the found history entry item, add its organization.id to the history table organization field for that row
• add another migration that sets the organization field as a pk field for the organization model

Requirements

• has organization field
• permissions can be by org
• If the history entry item does not exist, remove it
• Model delete signal which will remove history entries on parent model delete
  if no parent item, then use item_class

Tasks

• ☑️ remove test_view_different_organizaiton_denied test case from functional test cases HistoryPermissionsAPI
app/core/tests/functional/test_history/test_history_viewset.py
  This test case post the changes above, will once again be required as the model will be a Tenancy object.
