Update cloud scheduler permission to AWS equivalent

[faucomte97]

Task Description

There are a couple of API endpoints on the old system that require the Google Cloud Scheduler permission to run.
See the last 2 endpoints in api.py.

The permission is defined in the appengine repo.

We need to convert this to the AWS equivalent to prep the system for the switch to OTP.
We need to make sure it's in place, but not activated yet. We will activate it only when we perform the switch.

Alternatively, it might be easier to convert these 2 API calls to cron jobs.

Acceptance Criteria

Either:

• Update the permission to the equivalent role in AWS
  Or:
• Convert the 2 API calls to cron jobs
