When testing destroy, the test harness calls Refresh followed by Plan,
with the expectation that the resulting diff will be empty.
Data resources challenge this expectation, because they will always be
instantiated during refresh if their configuration isn't computed, and so
the subsequent diff will want to destroy what was instantiated.
To work around this, we make an exception that data resource destroy
diffs may appear in the plan but nothing else.
This fixes#6713.
cd0c452 contained a bug where the creation diff for a data resource was
put into a new local variable within the else block rather than into the
diff variable in the parent scope, causing a null diff to always be
produced.
This restores the expected behavior: a computed data resource appears in
the diff, so it can then be fetched during the apply walk.
Apparently there's been a regression in the creation of data resource
diffs: they aren't showing up in the plan at all.
As a first step to fixing this, this is an intentionally-failing test
that proves it's broken.

Update CHANGELOG.md
Update CHANGELOG.md
core: honor "destroy" diffs for data resources
provider/azurerm: `azurerm_network_interface` diffs didn't match during apply
providers/google: Don't fail deleting disks that don't exist.
Previously the "planDestroy" pass would correctly produce a destroy diff,
but the "apply" pass would just ignore it and make a fresh diff, turning
it back into a "create" because data resources are always eager to
refresh.
Now we consider the previous diff when re-diffing during apply and so
we can preserve the plan to destroy and then ultimately actually "destroy"
the data resource (remove from the state) when we get to ReadDataApply.
This ensures that the state is left empty after "terraform destroy";
previously we would leave behind data resource states.
When stage_name is not passed to the resource
aws_api_gateway_deployment a terraform apply will fail. This is
because the stage_name is required and not optional.
* Grafana provider
* grafana_data_source resource.
Allows data sources to be created in Grafana. Supports all data source
types that are accepted in the current version of Grafana, and will
support any future ones that fit into the existing structure.
* Vendoring of apparentlymart/go-grafana-api
This is in anticipation of adding a Grafana provider plugin.
* grafana_dashboard resource
* Website documentation for the Grafana provider.

The IP COnfiguration block of `azurerm_network_interface` didn't have a
hash created in a way that changes to the optional params were being
picked up:
```

```
This caused the following error:
```

Notice that the hash didn't change. This change adds the remaining optional params to the hash so that the hash id will change.

This allows the Update to work as expected :)
