status: Allow passing -verbose to meta status

A common issue when using nomad is needing to add in the object verb to
a command to include the `-verbose` flag.

This commit allows users to pass `-verbose` via the `nomad status` alias by
adding a placeholder boolean in the metacommand which allows subcommands
to parse the flag.
