* 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.
