Comment 3 for bug 1877254

Check on stable/train and the result is:

`neutron agent-list --sort-column binary` is sorted by neutronclient

`neutron agent-list --sort-key binnary` will be KO

DEBUG: keystoneauth.session REQ: curl -g -i -X GET http://overcloud.internal.vim1.local:9696/v2.0/agents?sort_key=binnary&sort_dir=asc -H "Accept:

e"

DEBUG: neutronclient.v2_0.client Error message: {"NeutronError": {"message": "[u'binnary'] is invalid attribute for sort_keys", "type": "HTTPBadRequest", "detail": ""}}

So we need implement it in neutron-server
