Post Processor Glance / Openstack

_This issue was originally opened by @imduffy15 as hashicorp/packer#2678. 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._

Hey All,

I've gone through some of the past pull requests and issues, I've found two around the topic of uploading images to openstack/glance directly from packer:
- https://github.com/mitchellh/packer/issues/540
- https://github.com/mitchellh/packer/pull/2410

Neither of these have been merged though. I have started writing my own one outside of packer and would love to get feedback, improve it, and eventually merge it in with master.

I have extended gophercloud to support the creation of images and the uploads of their binaries:
- https://github.com/monkeylittleinc/gophercloud/pull/1/files

Using this extended gophercloud I've built out a packer plugin to upload a qcow2 or raw file outputted by qemu up
- https://github.com/monkeylittleinc/packer-post-processor-glance/tree/iduffy-dev

I'm currently working on tests... Got any recommendations/examples on how to mock up the openstack service client? I took a brief look at other tests and they just seemed to avoid talking to external sources.

Thanks,
Ian.

Non vengono indicati file del repository né test. Inizia esaminando le issue precedenti di Packer a cui si fa riferimento, la modifica di gophercloud e il branch esterno packer-post-processor-glance; il lavoro sarebbe completato quando un post-processor OpenStack Glance definito e testato fosse integrato in questo plugin.

Scritto dal modello di indicizzazione a partire dal testo della issue.
