M058: OOI extern services integration to coi-services eoi

M058:
Integration of externalization services to coi-services, requires update to name in pyon.yml for tests. Allows EOI services to piggy back on CRUD operations in dataset management service. To actually leverage the services it requires that the importer_service be setup and running correctly, as well as other eoi services and that the eoi.meta.use_eoi_services be set to true in the pyon.yml file.
