get endpoints associated with a project will return 404 error if endpoint isnot exist

[wanghong]

This is a bug about OS-EP-FILTER extension.

First, I let an endpoint associated with a project via command:
curl -i -H "X-Auth-Token:admin" http://127.0.0.1:35357/v3/OS-EP-FILTER/projects/baafa1ac3d1340a59b6f2500f3071c24/endpoints/bf14cf0a1bec4304945f5025e3a74f6f -X PUT

Then, I delete the endpoint. When I list all the endpoints associated with the project I get a 404 error response:
{"error": {"message": "Could not find endpoint, bf14cf0a1bec4304945f5025e3a74f6f.", "code": 404, "title": "Not Found"}}

Also, if I let an endpoint associated with a project, and then delete the project. I get the 404 response too when I get projects associated with the endpoint.

I think here we can use revocation events to register the project and endpoint delete event and then delete the association in the callback.

    Clean up EP-Filter after delete project/endpoint

    For endpoint_filter extension we should remove all the endpoint
    to project associations when we delete the associated endpoint
    or project. Otherwise list_endpoints_for_project and
    list_projects_for_endpoint API will return 404 response if the
    associated endpoint or project has been deleted. Also, there will
    be a lot of dirty data remaining in the database.
