Add support for podman context as alias to podman system connection

Alias
podman --context -> podman --connection
podman context use -> podman system connection default
podman context rm -> podman system connection rm
podman context create -> podman system connection add
podman context ls ->podman system connection ls
podman context inspect ->podman system connection ls --json (For
specified connections)

Podman context is a hidden command, but can be used for existing scripts
that assume Docker under the covers.
