You could parametrize the "instance" variable to make this patch more reusable

Thanks! I did consider that, but I couldn't think of a scenario where we'd want to select from a different instance. I'm gonna leave it as-is for now, but happy to add that feature whenever the need arises.

This PR adds a new patch that picks the least busy backend that's also available on the open plan, regardless of which instance you're using.
We need this because we've added the
test_eagle_us-eastdevice to the instance we use for testing. The problem is that this device is always the least busy, so it'll be selected when we're doing our hardware runs. We can't just switch to the open instance for this test because I'm regularly out of credits and the priority is too low to run all the jobs in our time window.
