call neutron api twice for list subnet when count subnet quotas

[Min Sun]

When update a tenant's subnet quota, we have to list all existed subnets to count the minimal quota for subnet. In current code, it first lists none-shared subnets and then lists shared subnets. At last, put the two values together. It has to call neutron list subnet api twice. In fact, it can be done by one api call without shared parameter.

    usage: Ensure to count resources of a given project

    When retrieving resource usage, the current code calls subnet_list
    twice for shared=False/True, but 'shared' attribute of subnet is
    not defined in the Networking API and actually there is no need to
    use it (even though it works as expected accidentally).

    What we need here is to specify tenant_id as a query parameter
    with a single API to limit the scope to a given project.

    The same way can be used for network_list() and router_list() calls
    and it is more efficient. By doing so, we now need only one
    network_list() call.
