In short, the other "name" fields within the ServiceBusAdministrationClient are being changed to be explicitly queue_name, topic_name, etc. This should be consistent even for the "final named argument", as this makes it consistent with ARM call patterns.

Describe the solution you'd like
Follow the guidance in the aformentioned comment, normalize with other name fields and with -mgmt sdk.

Describe alternatives you've considered
The current status quo is the alternative, see the comment chain for discussion on relative merits.
