remoting layer defines no dependencies

The remoting layer depends upon legacy security realms but this dependency is not defined.

The layer named "remoting" should be updated to reference an elytron sasl-authentication-factory and the layer should depend upon the elytron layer.

There should be a second layer "legacy-remoting" which references the ApplicationRealm security realm and also this layer should have a dependency on the layer "application-security-realm".
