Support auto-add to specific queues

Is your feature request related to a problem? Please describe.

As network queues become more common and useful, users may wish to auto-upload their files to a network queue instead of the local one.

Describe the solution you'd like

1. A setting in OctoPrint that targets a specific queue when a file is added, and
2. An extension to the CPQ API that supports creating jobs/sets in a specific queue (not just the default one)

[smartin015]

The same validation that is performed when moving queues via the UI should also apply when adding new files via the API, i.e. profile inference should successfully constrain gcode files that are added.
