The "docker inspect" command can inspect any type of object, which would
require all possible endpoints to be contacted. By default, we don't
provide completion, but if a `--type` is passed, we provide completion
for the given type.
For example, `docker inspect --type container` will complete container
names, `docker inspect --type volume` will complete volume names and
so on.

Cobra now defines a CompletionFunc for the same, so we can alias
it to that, and stop using our own definition.
