Create a convenience method that wraps the remote primitive fetch Sonador dataobject method for retrieving imaging servers
Retrieving an imaging server reference is one of the most common operations in the client library, and the current method that uses fetch_sonador_dataobject
is cumbersome. A convenience method, get_imaging_server
(similar to some of the methods for fetching other types of resource objects), that wraps the lower level API should be introduced to make the client feel more cohesive.
