Get rid of hardcoded admin user uuid

The UUID is generated by `ocs init` now and stored in the config file.
To avoid that every ocis install uses the same UUID

Closes: #3524

 Change: Introduce `ocis init` and remove all default secrets
 
-We've removed all default secrets. This means you can't start oCIS any longer
-without setting these via environment variable or configuration file.
+We've removed all default secrets and the hardcoded UUID of the user `admin`.
+This means you can't start oCIS any longer without setting these via
+environment variable or configuration file.
 
 In order to make this easy for you, we introduced a new command: `ocis init`.
 You can run this command before starting oCIS with `ocis server` and it will
 bootstrap you a configuration file for a secure oCIS instance.
