when doing openstack limit list --project xyz_id,
CLI raising error unrecognized arguments, whereas
in api-ref document [1], user can pass project_id
as query param.This addresses the above issue, by
adding param --project in parser of LimitList.

Default pre-project quota is the number of IP addresses that can be
allocated from the subnet pool. For example, with a quota of 128,
I might get a 64 addresses subnet1, and 16 addresses subnet2,
and still have room to allocate 48 more addresses in the future.

Word choice of description for "host-evacuate-live" is slightly
different from that in novaclient ("migrate of" instead of "migrate off").
https://github.com/openstack/python-novaclient/blob/master/doc/source/cli/nova.rst#nova-host-evacuate-live
They are supposed to be exactly the same, so use "migrate off" to
keep consistent.
