Previously, it was comparing against the driver name passed in by the
caller. This could lead to subtle issues when using plugins, like
"plugin" vs. "plugin:latest".
Also, remove "conflict:" prefix to improve the error message.

When a conflict is found in the volume cache, check with the driver if
that volume still actually exists.
If the volume doesn't exist, purge it from the cache and allow the
create to happen.

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.
