Currently, some of the objects returned by using the ServiceLoader to load the RepositoryFactory services may in fact implement org.modeshape.jcr.api.Repositories. This is clumsy and incorrectly mixes content.

We need to clean up and separate the RepositoryFactory notion from the repository container notion. All of the RepositoryFactory implementations need to be cleaned up, and we should come up with how clients (like the web applications) can discover multiple repositories (e.g., by finding a container, perhaps with the ServiceLoader and a new RepositoryContainer interface).
