ZhiQiang Fan 196a747745 fix openstack cli command in doc manual
openstack role create requires a positional argument name, not optional.

also this patch removes endpoint trailing /, it is redundant and I still
remember once ago there is a bug reported for such issue, which leading
to urls like http://localhost:8777//v2/meters: double slashes
