Remove the User.isActive flag

[benmartin-coforma]

Description

This PR removes a half-implemented feature; the ability to deactivate users within the app.

Background: SEDS user data is split across internal (dynamodb) and external (IDM) systems. In non-dev environments, users must exist in IDM before they can log in to SEDS. Once they exist in SEDS, details like their state list and role can be added or changed in dynamodb; from that point forward we consider dynamo to be authoritative. The isActive flag was intended to be such a detail, but even though we added code to manage this flag, we never changed any part of the app to read the flag. Rather than completing that feature, we will henceforth rely on IDM for user deletion/deactivation.

This allows us to remove a good deal of code:

1. The UI elements that controlled the flag
2. The UI elements that displayed the flag
3. The UI functions which called the API to set the flag
4. The API endpoint to set the flag
5. Lots of references to the flag

Additionally, this PR contains a migration to purge the isActive flag from all existing users. A list of all users which had isActive set to false has been collected and is in the Business Owners' hands; they will do whatever is appropriate for those users in IDM and in SEDS. Once this migration has run in all environments, there will be no lingering traces of isActive anywhere in the app.

How to test

Cloudfront url: https://d3k0z4kfh0z5fc.cloudfront.net/

1. Log in as an admin
2. Go to the user list
   • The isActive flag should not be in the table
3. Export the user list to excel
   • The isActive flag should not be in the spreadsheet
4. Click in the user list to edit a user
   • The isActive flag should not be on the page
5. Make a change to the user and save it
   • The save should be successful

(After merging into master)

1. Confirm that the master-auth-user table has isActive flags on the users
2. Run the migration
3. Confirm that the isActive flags are now gone
