* add docs
* fix potential bug

This change uses a different  as part of the TestArchive output path to fix
an intermittently failing test case on Windows caused by using the same
output name across test cases.

Originally tired to use t.TempDir() to gt a temp path but ran into
errors with parsing the config on Windows.

```
Unable to parse test config: invalid character 'U' in string escape code
```

Closes #10903

* Add basic support for build_labels argument

* Update support for build_labels configuration argument

* Update complete test-fixture with a build_labels configuration
* Add test for deprecated labels argument
* Add deprecation for hcp_packer_registry.labels

When using the now deprecated labels argument of the new bucket_labels a
Warning will be presented to the user.

```
~>  HCP_PACKER_BUILD_FINGERPRINT=356786543567865456789656789 packer
build source.pkr.hcl
Warning: the argument hcp_packer_registry.labels has been deprecated and will be removed in a future release; please use hcp_packer_registry.bucket_labels
```

When trying to use both bucket_labels and labels together an error is
presented to the user.
```
~>  HCP_PACKER_BUILD_FINGERPRINT=ss6786543567865456789656789 packer
build source.pkr.hcl
Error: hcp_packer_registry.labels and hcp_packer_registry.bucket_labels are mutely exclusive; please use the recommended argument hcp_packer_registry.bucket_labels
