I forgot to add `Computed: true` when I made the "key_name" field
optional in #1751.
This made the behavior:
* Name generated in Create and set as ID
* Follow up plan (without refresh) was nice and empty
* During refresh, name gets cleared out on Read, causing a bad diff on
subsequent plans
We can automatically catch bugs like this if we add yet another
verification step to our resource acceptance tests -> a post
Refresh+Plan that we verify is empty.
I left the non-refresh Plan verification in, because it's important that
_both_ of these are empty after an Apply.
Each acceptance test step plays a Refresh, Plan, Apply for a given
config. This adds a follow up Plan and fails the test if it does not
come back empty. This will catch issues with perpetual, unresolvable
diffs that crop up here and there.
This is going to cause a lot of our existing acceptance tests to fail -
too many to roll into a single PR. I think the best plan is to land this
in master and then fix the failures (each of which should be catching a
legitimate provider bug) one by one until we get the provider suites
back to green.
