1. add new registry api under resources.kubesphere.io/v1alpha3 2. deprecate registry api v1alpha2 Registry API v1alpha2 uses docker client to authenticate image registry secret, which depends on docker.sock. We used to mount host `/var/run/docker.sock` to deployment. It will prevent us imgrating to containerd since no `docker.sock` exists. Registry API v1alpha3 comes to rescure, it wraps library go-containerregistry and compatible with docker registry, Harbor etc.
