REST/Realtime APIs available during bootstrapping

Describe the Bug
When starting up for the first time, the backend services system will bootstrap the convergence database and domains. While this is happening, the system is not complete functional yet. However, the realtime and rest APIs bind and make themselves available; yet they will throw errors if called. We should defer that starting of the REST and Realtime until the system is bootstrapped and/or we should ensure the backend services are not going to respond.

This can manifest itself in a timeout looking for the backend, or messages that No local DomainPersistenceManager found
