Because novaclient need to get each flavor's extra_specs detail, in fact
it make thousands of request to nova-api. which make the command very
slow.
If I just hit the REST API by
$ time http get localhost:8774/v2/33027e9bc0914bc88414bae31c6ecc9f/flavors
....

],

}
]
}

The response time is fine, but the response flavors is not complete(
just to f-1899) neither.
