This fix tries to address the issue mentioned in Docker Remote API where the examples for creating a container (`POST /containers/create`) with volumes were incorrect. In the previous remote API document, the `Mounts` fields was used for volume creation yet since v1.20 `Volumes` should be used. This fix fixes #21335.
