`memorySwap` in createContainer seems to be ignored

[bitc]

I haven't investigated this thoroughly, but it appears that the memorySwap configuration documented here:

https://hackage.haskell.org/package/docker-0.6.0.6/docs/Docker-Client-Types.html#t:ContainerResources

seems to be ignored by docker, and when inspecting the running container it always has:

"MemorySwap": -1,

I will try to investigate further, but I am posting this here in the meantime in case anyone else has any more information.

Thank you
