Remove no longer needed bootstrap code (#5057)

This we moved the settings service to the metadata storage with its
own gateway and permissions service, we no longer need the hardcoded
initial replies in order to bootstrap the role assignments.

This fixes a panic in the settings service when the first request to
the service is a read request on anything else but an existing role or
assignment.
