Add HCP Packer support for the QEMU builders

[afretwell]

Overview of the Issue

When I add the hcp_packer_registry block to my builds block I see that my build instantly fails when reaching the hcp_packer_registry block. When I do not add the hcp_packer_registry block I am able to successfully create my Ubuntu image with no issues, I just cant push it to HCP Registry. I have logged into HCP cloud and was able to see that my build is being queued to hcp registry, but always results in failed status because of the issue Im being faced with. All of my parameters from my hcp_packer_registry block are making being sent to hcp successfully but my image is not for some reason. Ive even tried removing all parameters with the exception of bucket_name but still results in this block failing 100% of the time on multiple systems. Assistance would be greatly appreciated.

Reproduction Steps

1. Add the HCP_CLIENT_ID and HCP_CLIENT_SECRET env vars
2. Add the hcp_packer_registry block to your build block in your hcl2 file
3. Run PACKER_LOG=1 packer build ubuntu.pkr.hcl

Packer errors out after post-processors end and returns the error:

==> qemu.ubuntu: Running post-processor:

Hi there @afretwell thanks for reaching out. Your template is setup correctly. The issue you are running into here is that the QEMU builder is not generating HCP Packer images, as they require some additional metadata.

That said, only a handful of Packer builders work with HCP Packer. I'm going to use this issue as a feature request to add HCP Packer image publishing support to the QEMU builder.

Amazing to hear, thank you, I'm sure it's not the top of priorities, but is there an average turnaround time for enhancements like this one?

Any update on this feature for qemu builder?
