Goal: 

• Create an api the UI can use that will start a task to:
• Finalize one or more uploads into artifacts
• Convert one or more uploaded artifacts into rpms
• Create a new repository version in pulp with those rpms
• Create a snapshot

• The task should utilize the following apis:
  • Commit the uploads: https://pulpproject.org/pulpcore/restapi/#tag/Uploads/operation/uploads_commit

• • Create rpm: https://pulpproject.org/pulp_rpm/restapi/#tag/Content:-Packages/operation/content_rpm_packages_create
  • Create a repository version  https://pulpproject.org/pulp_rpm/restapi/#tag/Repositories:-Rpm/operation/repositories_rpm_rpm_modify

• This api should look something like:
• (example URL) POST /api/content-sources/v1/repositories/:UUID/snapshots/uploads/

It should take a list of artifact HREFs, something like:

{
  uploads: [
       { 
         upload_href: "href1",
         sha256sum: "abcdefgh"
        }  
  ]
}

The response would be a task response (full structure of the task as we return from our tasks api today), and this task should be saved as the 'last_snapshot_task' on the repository configuration
