Makes `docker volume ls` and `docker volume inspect` ask the volume drivers rather than only using what is cached locally. Previously in order to use a volume from an external driver, one would either have to use `docker volume create` or have a container that is already using that volume for it to be visible to the other volume API's. For keeping uniqueness of volume names in the daemon, names are bound to a driver on a first come first serve basis. If two drivers have a volume with the same name, the first one is chosen, and a warning is logged about the second one. Adds 2 new methods to the plugin API, `List` and `Get`. If a plugin does not implement these endpoints, a user will not be able to find the specified volumes as well requests go through the drivers. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
