Fixes #157 on server-side

Main changes as per design docs:

• Rename sources to registries
• Allow multiple registries from:
• ConfigMap (operator-side)
• Git
• Registry API
• File (server side)
• Managed registry is another type of registry (server-side)
• Remove the explicit type field to simplify the configuration

Next PR will handle the operator updates
