Per python guidelines: https://azure.github.io/azure-sdk/python_design.html#python-client-splat-args

• mgmt update methods should take updateable fields as kwargs (e.g. update_queue should perhaps take DeleteOnIdle or what-have-you as a kwarg to override, if specified, the one in the primary description object)
• For mgmt (and non-mgmt) functions where an object is taken, also accept a dict representing that object.
