Implement gRPC calling from DCM to RSync

And address any issues faced.

This will push the etcd data created via DCM API into the resource synchronizer which will then create the necessary k8s resources (that have already been populated by DCM in etcd).

• This includes modifying applyHandler.
• Pre-process all k8s resources that include a dot (.) in their key name as dots are not supported in MongoDB thus considerably breaking things and preventing resource quotas (e.g.) from actually getting created in Kubernetes.
