Adds a stanza for both Host Volumes and CSI Volumes to the the CLI
output for `nomad alloc status`. Mostly relies on information already
in the API structs, but in the case where there are CSI Volumes we
need to make extra API calls to get the volume status. To reduce
overhead, these extra calls are hidden behind the `-verbose` flag.
