no longer send dockerconfigjson if container.HostedRegistry is true

[acornett21]

• Fixes: No Longer Send Docker Config for Red Hat Hosted Registries #817
• Add in a check container to see if RH hosts the registry, and if so no longer send the dockerconfigjson to pyxis
  • This prevents uploading dockerfiles that clair/registry-proxy would be unable to use to pull the image
• Added unit tests to cover this logic
• Manually tested in UAT against projects 6334bcc6580d0bddc451107c and 6334c74d387cd5060b70dce8
