DeckHand Client Returning 'NoneType' object

[eanylin]

We have a valid revision in deckhand that was created using Shipyard CLI

We will end up with NoneType object error if we try and make use of the deckhand client to retrieve the revision. It is difficult to troubleshoot this kind of problems as we are not getting much information on why the deckhand client error out. We will need better logging in order to identify the issue causing this error

Note that communications between airflow workers and deckhand is via the internal interface and not public interface. Hence we need to set the endpoint_type to internal instead of using the default public.
