Per service relying party IDs

This pull request adds support for per service relying party ID configuration. Configuration is controlled by the services registry as described in the README.md
Also, just a tiny remark that if someone would want to use this feature (with this extra attributes map) they'd need to use JSON svc registry (capable of dealing with this type) which they would depend on cas-addons anyway.
