Move the EmbeddedFederation and its supporting classes into the src/test side of the code base.

The EmbeddedFederation is used by many of the test suites and makes it simpler to test some things without jini or zookeeper online, but it is not supported as a deployment architecture
- single machine federation deployments are handled exactly cluster based federation deployments.

Move the EmbeddedFederation to the to the test side of the code base. This includes at least the following classes: AbstractEmbeddedLoadBalancerService, AbstractEmbeddedDataService, AbstractEmbeddedTransactionService, EmbeddedFederation, EmbeddedClient, EmbeddedMetadataService, etc.
