Use version package to track all versions
* Server, bindings, and CLI all now pull version information from version package. * Current /libpod API version slaved to podman/libpod Version * Bindings validate against libpod API Minimal version * Remove pkg/bindings/bindings.go and updated tests Fixes: #9207 Signed-off-by: Jhon Honce <jhonce@redhat.com>
