Command to set platform_admin status

[sastels]

Description

As a platform admin, I need to be able to make others platform admins without manually editing the database.

WHY are we building?

Currently the only way to make someone a platform admin is to open a writeable connection to the database and manually edit the record for that user. This is dangerous.

WHAT are we building?

A flask command to toggle the platform admin flag for a given user.

VALUE created by our solution

Improved security and reliability: We no longer have to manually edit the database to do this fairly common task.

Acceptance Criteria

• [x] A flask command to toggle the platform_admin flag exists.

QA Steps

• [x] log into an api or celery pod
• [x] run the command FLASK_APP=application.py flask command admin -u <your email address> --off
• [x] clear the users cache (or log out and in) and verify that you are no longer an admin!
• [x] run the command FLASK_APP=application.py flask command admin -u <your email address>
• [x] log out and into Notify again and verify that you are once more an admin.

I had originally changed admin to add a toggle to the user's information page in the platform admin view, but decided that this opened us to a potential escalation of privileges attack if endpoints were not sufficiently secure. So I then decided that it would be better as a flask command that could only be run from within the k8s cluster (or, at least, something connected to the database).
