Request email from open id clients, as this would provide a handy way to uniquely reference users when assigning to groups.
During Login do a lookup on email if possible -- so that permissions assignments based on email can be connected when sigining in through openid.
Don't use "open_id" for the service name on user accounts, use the iss string provided through open id, this will allow us to support more than one open id platform.
Update the KeyCloak configuration so it is able to return email addresses for users -- which will make permission assignment easier in the future.
Removed several unused commands in the user_service class.
-------
* Remove unnecessary packages from dockerfile for the demo-connect proxy.
* Rename an environment variable that mentioned Status.im in what is now a generic connector.
* Fixed a spelling mistake.
Removing all calls to open id's user_info endpoint - as these are unncessiary.
Adding a users section to the permission files -- so we can handle all user/group/permissions in one file when needed.
There was a very confusing is_admin function on the user model that needed killin.
