terraform: more specific resource references
terraform: outputs need to know about the new reference format
terraform: resources w/o a config still have a referencable name
this PR fixes a flakyness in the `scaleway_volume_attachment` resource, as
described below:
when attaching/ detaching a volume from a `scaleway_server`, the server needs to
be stopped. even though the code already waits for the server to be stopped, the
`PatchServer` calls gets a `400 server is being stopped or rebooted` error
response.
If the API returns the `400` we bail, leaving terraform in a broken state.
Assuming this is the only error that the API might return to us, as the payload
itself is correct, this retry behaviour should fix the issue.

This makes the old graph also prune orphan outputs in modules.
This will fix shadow graph errors such as #9905 since the old graph will
also behave correctly in these scenarios.
Luckily, because orphan outputs don't rely on anything, we were able to
simply use the same transformer!
Fixes#9920
This was an issue caught with the shadow graph. Self references in
provisioners were causing a self-edge on destroy apply graphs.
We need to explicitly check that we're not creating an edge to ourself.
This is also how the reference transformer works.
When configuring an instance's attached disk, if the attached disk has
both the disk and type attributes set, it would previously cause
terraform to crash with a nil pointer exception. The root cause was that
we only instantiate the InitializeParams property of the disk if its
disk attribute isn't set, and we try to write to the InitializeParams
property when the type attribute is set. So setting both caused the
InitializeParams property to not be initialized, then written to.
Now we throw an error explaining that the configuration can't have both
the disk and the type set.
Fixes#6495.
