* feat(cluster): initial commit for scale-out cluster Signed-off-by: Ramkumar Chinchani <rchincha@cisco.com> * feat(cluster): support shared storage scale out This change introduces support for shared storage backed zot cluster scale out. New feature Multiple stateless zot instances can run using the same shared storage backend where each instance looks at a specific set of repositories based on a siphash of the repository name to improve scale as the load is distributed across multiple instances. For a given config, there will only be one instance that can perform dist-spec read/write on a given repository. What's changed? - introduced a transparent request proxy for dist-spec endpoints based on siphash of repository name. - new config for scale out cluster that specifies list of cluster members.
