Because we now rely on HIL to do the computed calculation, we must make
sure the type is correct (TypeUnknown). Before, we'd just check for the
UUID in the string.
This changes all variable returns in the interpolater to run it through
`hil.InterfaceToVariable` which handles this lookup for us.
Also added a test to prove that the computed value gets set
```
% make testacc TEST=./builtin/providers/aws TESTARGS='-run=TestAccAWSDBInstance_basic'
==> Checking that code complies with gofmt requirements...
go generate $(go list ./... | grep -v /terraform/vendor/)

```
This uses the new NodeApplyableProvider graph nodes. This will just make
it easier for us in the future to adopt new graph transforms by starting
to use the new ones here.
Fixes#7774
This modifies the `import` command to load configuration files from the
pwd. This also augments the configuration loading section for the CLI to
have a new option (default false, same as old behavior) to
allow directories with no Terraform configurations.
For import, we allow directories with no Terraform configurations so
this option is set to true.
The primary change here is to expect that Config contains computed
values. This introduces `unknownCheckWalker` that does a really basic
reflectwalk to look for computed values and use that for IsComputed.
We had a weird mixture before checking whether c.Config was simply
missing values to determine where to look. Now we rely on IsComputed
heavily.
This makes all the computed stuff "just work" since HIL uses the same
computed sentinel value (string UUID) and the type differentiates it
from a regular string.
The map output from the module "mod" loses the computed value from the
template when we validate. If the "extra" field is removed from the map,
the validation fails earlier with map "does not have any elements so
cannot determine type".
Apply will work, because the computed value will exist in the map.
