check the url format when create endpoint

[wanghong]

Currently, the url allows any parameters when create endpoint, such as:
curl -i -H "X-Auth-Token:admin" -H "Content-Type:application/json" http://127.0.0.1:35357/v3/endpoints -d '{"endpoint":{"interface":"test","service_id":"d893b85ae4f842d5bb1727e271cf5be3","url":"111"}}'

HTTP/1.1 201 Created
Vary: X-Auth-Token
Content-Type: application/json
Content-Length: 252
Date: Tue, 25 Feb 2014 03:13:30 GMT

{"endpoint": {"links": {"self": "http://192.168.70.108:5000/v3/endpoints/81638ad18b9e4495aac576c006c1fed1"}, "url": "111", "region": null, "interface": "test", "service_id": "d893b85ae4f842d5bb1727e271cf5be3", "id": "81638ad18b9e4495aac576c006c1fed1"}}

Should we add a check that the url parameter must be url format like?

    Implement validation on the Catalog V3 API

    Use JSONSchema to validate CRUD operations on V3 Catalog resources. This
    includes wrapping the create and update methods for Regions, Services,
    and Endpoints. This change removes functionality specific to the Catalog
    API for validating parameters for incoming requests.
