*** Reason for rollback ***
It's still having the same issues from b/79463634 in sandbox, so we don't want to deploy it to prod.
*** Original change description ***
Switch pubapi/default service to basic scaling in prod/sandbox
Also goes back up to 100 max instances.
Hopefully this'll work better this time.
