docker volume inspect does not show volume options

[pdevine]

If you create a volume with options, docker inspect doesn't output any of the information, making it difficult to determine how a volume was created.

Here's the current output:
[ { "Name": "foo", "Driver": "local", "Mountpoint": "/var/lib/docker/volumes/foo/_data", "Labels": {} } ]

I would expect another "Options" key which has a value like {"": "", ...} for each of the options specified.

Any love for this issue? @cpuguy83

Just requires persisting options in the volume db so we can retrieve them along with labels.
Feel free to make a patch, should be fairly straight forward.
