Default dask nodes to be same config as notebook nodes in azure

[yuvipanda]

The documentation said this is what already happens, but
the documentation was a lie.

This helps us keep config simple and easy to manage.

On the only Azure hub we run, this is a noop.

No changes. Your infrastructure matches the configuration.

Your configuration already matches the changes detected above. If you'd like to update the Terraform state to match, create and apply a refresh-only plan:
  terraform apply -refresh-only
Releasing state lock. This may take a few moments...

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
