podmanV2: implement push

* Implement `podman-push` and `podman-image-push` for the podmanV2
  client.

* Tests for `pkg/bindings` are not possible at the time of writing as we
  don't have a local registry running.

* Implement `/images/{name}/push` compat endpoint. Tests are not
  implemented for this v2 endpoint.  It has been tested manually.

General note: The auth config extraction from the http header is not
implement for push.  Since it's not yet supported for other endpoints
either, I deferred it to future work.
