Ansible Synapse deployment when password login is disabled

[Adrien Touzouli]

In prod we want simple login password to be disabled so users have the choice between PSC and EIMIS connect.
There's several steps in Synapse config:

• first config to get started
• create an admin user
• upload pictos for oidc buttons
• manage discovery rooms (create dummy-user, invite users from federation)
• an extraconfig step mainly to configure picto for oidc buttons after this step pods are restarted

DoD

in an env where password login is disable and the stack is already created, it's possible to go through the steps in which the admin user token is needed: auth-button and discovery-room

how?

• Ideally there's a way to configure oidc picto without having to restart the pods but don't know how to do that 🤷
• easy way: reset extraconfig map to enable password login and restart synapse before 1st step (if already deployed)
• better : only do first-admin auth-button discovery-room when deploying from scratch

Additionally It would be nice to restart pods only if matrix-synapse or matrix-synapse-extraconfig configmap has been changed

also take advantage to remove

  extraVolumes:
    - name: s3-media-repo-module
      configMap:
        name: s3-media-repo-module

in extra config
