[keycloak-user] User impersonation - JWT

The way it works is:

* Admin impersonate user
* SSO for browser is now switched to be authenticated as the user rather
than the admin
* Admin can now login to any application and would automatically be logged
in as the impersonated user

So it's transparent to the applications and they don't need to deal with
impersonation in a special way.
