When a cluster doesn't have a leader, the `nomad operator debug`
command can safely use stale queries to gracefully degrade the
consistency of almost all its queries. The query parameter for these
API calls was not being set by the command.
Some `api` package queries do not include `QueryOptions` because
they target a specific agent, but they can potentially be forwarded to
other agents. If there is no leader, these forwarded queries will
fail. Provide methods to call these APIs with `QueryOptions`.
