Backport of Horizon fix for updating disabled security groups quotas

Our neutron plugin doesn't support security group since it's an optional extension. But when I create project from horizon, i had the following error:

Request body: {u'quota': {u'subnet': 10, u'network': 10, u'floatingip': 50, u'securi\

I traced the code, in openstack_dashboard/dashboards/admin/projects/workflows.py:

class UpdateProjectQuota(workflows.Step):
    action_class = UpdateProjectQuotaAction
    depends_on = ("project_id",)
    contributes = quotas.QUOTA_FIELDS

it sends everything in quotas.QUOTA_FIELDS to neutron. The quotas.QUOTA_FIELDS has hard coded 'security_group' and 'security_group_rule' in it. So even security group is an optional extension and it's not supported in our plugin, but 'security_group' and 'security_group_rule' still presents in the request and cause the error.
