update/delete/create resource with reference to resource by name

[yong sheng gong]

TO improve usability, we can use name to reference resource via name_or_id to do modification, deletion and creation:
quantum net-update name_or_id --key value
quantum net-delete name_or_id
quantum subnet-create networkname_or_id 10.0.1.0/24

    Add name or id to quantum cli commands.
    Bug #1030180

    We first lookup the resource id via id if it looks like an id.
    If we cannot find it via id, we will look it up via name.
    All of the update/show/delete support reference resource via name or id.
    To create port/subnet, we can refercen network via network's name.
    Also in port creation, we support reference subnet in fixed_ip via its name.

    quantum_test.sh is added to test the command lines after running 'python setup.py install'
