baymodel-update doesn't support baymodel name

[Eli Qiao]

We need to fix this:

taget@taget-ThinkStation-P300:~/devstack$ magnum baymodel-update swarmmodel replace docker_volume_size=1
ERROR: Invalid input for field/attribute baymodel_uuid. Value: 'swarmmodel'. unable to convert to uuid (HTTP 400)

taget@taget-ThinkStation-P300:~/devstack$ magnum baymodel-update feebf450-fa28-4aac-9d09-986a961ee89a replace docker_volume_size=1

    API: use baymodel_ident to update a baymodel

    Currently, we can not update a baymodel with baymodel name, this patch fixes
    it by passing baymodel_ident instead of using baymodel_uuid.
