Neutron: List quotas doesn't show fully parameters

Networking API v2.0 extensions (Quotas extension): http://developer.openstack.org/api-ref-networking-v2-ext.html

Issue: Lists quotas for tenants who have non-default quota values that doesn't show fully parameters (not has "security_group_rule", "security_group" and "subnetpool" attributes) on JSON Response.
For example:
Current:
{
    "quotas": [
        {
            "subnet": 10,
            "network": 10,
            "floatingip": 50,
            "tenant_id": "b7445f221cda4f4a8ac7db6b218b1339",
            "router": 10,
            "port": 30
        }
    ]
}

It should be updated as below:

{
    "quotas": [
        {
            "subnet": 10,
            "network": 10,
            "floatingip": 50,
            "tenant_id": "b7445f221cda4f4a8ac7db6b218b1339",
            "subnetpool": -1,
            "security_group_rule": 100,
            "security_group": 10,
            "router": 10,
            "port": 30
        }
    ]
}
