List ports fails due to dummy pod entry

[Zhiyuan Cai]

How to reproduce:

Add a dummy pod entry via pod API:

curl -X POST http://127.0.0.1:19999/v1.0/pods -H "Content-Type: application/json" -H "X-Auth-Token: $token" -d '{"pod": {"pod_name": "RegionTwo", "az_name": "az2"}}'

where "RegionTwo" is not a valid Keystone region with no endpoints registered.

Then issue port list request to central Neutron server, get InternalServerError, the log shows

"EndpointNotFound: Endpoint for neutron in c1d68184-1498-4576-a802-b1e01e37adda not found"

    Fix list port failure due to dummy pod entry

    1. What is the problem?
    If a dummy pod whose region doesn't register any endpoints in Keystone
    is created via pod API, port list request to central Neutron server will
    fail with EndpointNotFound error.

    2. What is the solution to the problem?
    Instead of raising EndpointNotFound error, client returns default value
    (None or empty list).

    3. What the features need to be implemented to the Tricircle
       to realize the solution?
    Handle functions in client module return default value when endpoint
    url for given service and pod is not found in Keystone.
