Goal:

• Be able to build images with repositories from content-sources that are deemed 'upload' repositories and have user supplied RPMs
• Can be built using 'Use latest content' or via a snapshot date
• Client is configured with the yum repository config pointing to the relevant content URL (but disabled, as it requires registration)

Acceptance Criteria:

• UI is updated to pull list of repositories from content-sources to include origin=external,upload
  • this is adding an 'upload' to the list
• If an upload repo is selected with "use latest content", use the 'latest_snapshot_url' on the repository object.  This URL will always point to the latest snapshot
  • This URL will need to be converted to the mtls turnpike URL
• If an upload repo is selected with a snapshot date, use the snapshots like we already do today
• Searching for packages in upload repos should use the repo UUID instead of url (since upload repos don't have urls).
