Describe the solution you'd like

• I think we can enable REGISTRY_STORAGE_DELETE_ENABLED=true when we start the registry. (

  caprover/src/user/system/SelfHostedDockerRegistry.ts

  Line 92 in dc2a5b6

  function createRegistryServiceOnNode(nodeId: string) {

  )
• Add API to list of repository in the private registry
• Add API for list image in each repository in the private registry
• Add API to delete the image in the private registry.
