Add a new CLI utility, falcon-print-routes, that takes in a module:instance_or_callable,
introspects the routes, and prints the results to stdout.
Example:
$ falcon-print-routes commissaire.testroutes:a
-> /api/v0/status
-> /api/v0/cluster/{name}
-> /api/v0/cluster/{name}/hosts
-> /api/v0/cluster/{name}/hosts/{address}
