The `-type` option for `volume status` is a UX papercut because for many
clusters there will be only one sort of volume in use. Update the CLI so that
the default behavior is to query CSI and/or DHV.
This behavior is subtly different when the user provides an ID or not. If the
user doesn't provide an ID, we query both CSI and DHV and show both tables. If
the user provides an ID, we query DHV first and then CSI, and show only the
appropriate volume. Because DHV IDs are UUIDs, we're sure we won't have
collisions between the two. We only show errors if both queries return an error.
Fixes: https://hashicorp.atlassian.net/browse/NET-12214
Adds dynamic host volumes to argument autocomplete for the `volume status` and
`volume delete` commands. Adds flag autocompletion for those commands plus
`volume create`.

* Fix plugin capability sorting.
The `sort.StringSlice` method in the stdlib doesn't actually sort, but
instead constructs a sorting type which you call `Sort()` on.
* Sort allocations for plugins by modify index.
Present allocations in modify index order so that newest allocations
show up at the top of the list. This results in sorted allocs in
`nomad plugin status :id`, just like `nomad job status :id`.
* Sort allocations for volumes in HTTP response.
Present allocations in modify index order so that newest allocations
show up at the top of the list. This results in sorted allocs in
`nomad volume status :id`, just like `nomad job status :id`.
This is implemented in the HTTP response and not in the state store
because the state store maintains two separate lists of allocs that
are merged before sending over the API.
* Fix length of alloc IDs in `nomad volume status` output
Volume IDs are not UUIDs, so truncating them to the short ID isn't really
necessary and makes for especially awkward UX when per-alloc volumes are in
use.
