instance_id output should be the latest created instance

[cuotos]

if a change is required to the instance, the tf lifecycle will make sure a new one is created before terminating the other one.
But the instance_id output doesnt update until the end of the run.

this could possibly be fed from a data object listing all the diagnostic instances and just returning the ID of the most recent one, so that you can connect to it before the old has been destroyed.
