Feature Request: More verbose description on the type of tag being applied

_This issue was originally opened by @shapp1 as hashicorp/packer#7772. It was migrated here as a result of the [Packer plugin split](https://github.com/hashicorp/packer/issues/8610#issuecomment-770034737). The original body of the issue is below._

I'm utilizing run_tags, spot_tags, run_volume_tags, and tags for the aws builder. The console shows the tagging process like so:

==> amazon-ebs: Adding tags to source instance
amazon-ebs: Adding tag: "Owner": "John Doe"
amazon-ebs: Adding tag: "OS": "linux"
=> amazon-ebs: Adding tags to source EBS Volumes
amazon-ebs: Adding tag: "Owner": "John Doe"
amazon-ebs: Adding tag: "Environment": "hr"
amazon-ebs: Requesting spot instance 't2.small' for: 0.0175
amazon-ebs: Waiting for spot request (sir-xxxxxxxx) to become active...
amazon-ebs: Adding tag: "App": "test-app-01"
amazon-ebs: Adding tag: "Beta": "true"
[..etc..]

My request is that packer output more verbose tagging text, for example, "Adding spot_tag "blah": "blah"", "Adding run_tag "blah": "blah", etc... to let the user know which block of tags to look at if a change is needed.

Thanks
