Mirror package registry servers
Problem to solve
Many customers have multiple package registries setup across multiple applications. They would like to use the GitLab Package Registry but still need to keep their registry in another source. Or they have older registries that aren't actively being used but they don't want to remove for archiving purposes.

Proposal
Implement a push and pull mirror to allow customers to ensure their other registries stay in sync and are always available.
