This change temporarily renames the type of the packer-image-iteration
datasource to prevent it from being automatically registered by the
Packer plugin tooling. The datasource is fully functional, but not quite
ready for full usage. It will be updated in a future release.
* Update handling of registry artifacts
This change uses the github.com/hashicorp/packer-plgin-sdk/packer/registryimage for querying
Artifact State for HCP Registry Image metadata. To handle the conversion
of the RPC response, mapstructure was introduced to conversion state
data into an registryimage.Image before publishing to a image bucket.
* Update to use registry image from packersdk
* Rename internal registry service pkg
* Update vendored plugins to latest version
* The latest release of Amazon, GoogleCompute, and Azure have support
for publishing images to the HCP Packer registry.

create a null data source for testing. We can choose to document if we want to, but it's a convenience for us
add a test to catch cyclic datasource dependency, update tests to include out of order data sources, and update the code to clean up the returned diagnostics generated from the recursive evaluation
