Packer: Feature Request: Return Azure image id

[akomakom]

There appears to be no programmatic way of getting the ID of the resultant image when building managed images with the Azure Builder.

For example:

"managed_image_name": "jenkins-centos7-{{isotime \"2006-01-02T1504\"}}"
would produce an image with the given name, but there is no way for me to determine the final name short of parsing the console output.

I've tried the recommendation in #5117 (to use the manifest post-processor), but it outputs a blank artifact_id:

   {
      "name": "azure-arm",
      "builder_type": "azure-arm",
      "build_time": 1538052650,
      "files": null,
      "artifact_id": "",
      "packer_run_uuid": "2c711ee4-6548-7a81-6a98-2120c99d43cb"
    }

(with AWS, the artifact_id is indeed populated)

What I'd like, at the very least:

   {
      "name": "azure-arm",
      "builder_type": "azure-arm",
      "build_time": 1538052650,
      "files": null,
      "artifact_id": "jenkins-centos7-2006-01-02T1504",
      "packer_run_uuid": "2c711ee4-6548-7a81-6a98-2120c99d43cb"
    }

What I'd like, ideally:

   {
      "name": "azure-arm",
      "builder_type": "azure-arm",
      "build_time": 1538052650,
      "files": null,
      "artifact_id": "/subscriptions/xxxxxxxxxxxxxxxxxxxx/resourceGroups/XXXXXXXX/providers/Microsoft.Compute/images/jenkins-centos7-2006-01-02T1504",
      "packer_run_uuid": "2c711ee4-6548-7a81-6a98-2120c99d43cb"
    }

(Full image ID is returned)

My current workaround is to pass the name of the new image to packer as a user variable instead of letting the template generate it. This is not ideal because it's not consistent across builders (for example, AWS builder does not have any correlation between the "ami_name" and the resultant ami id) so I'd rather not make the assumption that this will always work even in Azure.

I've made a PR that should fix this (linked above); if you let me know your host architecture (linux, windows, or osx), I can provide you with a build of Packer that has this patch so you can test it out.
