Role based on level

[ArmandBriere]

Is your feature request related to a problem? Please describe.
We have ranks and level, we want to associate special role to a level

Describe the solution you'd like

• pubsub function in Go that read the Firestore DB to find which role a specific use should have
• If some roles are missing -> add them
• Find a way to execute this function for users that are already here
