Make use of same socket expose for both podman and docker client #3020
Description
As of now we do something following but if we are exposing the socket then we might just use it for both podman/docker client instead using ssh implementation for podman and socket expose for docker.
$ ./crc podman-env
export PATH="/Users/prkumar/.crc/bin/oc:$PATH"
export CONTAINER_SSHKEY="/Users/prkumar/.crc/machines/crc/id_ecdsa"
export CONTAINER_HOST="ssh://core@127.0.0.1:2222/run/user/1000/podman/podman.sock"
export DOCKER_HOST="unix:///Users/prkumar/.crc/machines/crc/docker.sock"
$ podman --url unix:///Users/prkumar/.crc/machines/crc/docker.sock images --log-level debug

We can have something like and expose both root/rootless socket.
$ ./crc podman-env
export PATH="/Users/prkumar/.crc/bin/oc:$PATH"
export CONTAINER_HOST="unix:///Users/prkumar/.crc/machines/crc/docker-rootless.sock"
export DOCKER_HOST="unix:///Users/prkumar/.crc/machines/crc/docker-rootless.sock"
$ ./crc podman-env --root
export PATH="/Users/prkumar/.crc/bin/oc:$PATH"
export CONTAINER_HOST="unix:///Users/prkumar/.crc/machines/crc/docker.sock"
export DOCKER_HOST="unix:///Users/prkumar/.crc/machines/crc/docker.sock"
