no testcases to cover the region creation with invalid id

[Dave Chen]

Regions use ID differently. The user can specify the ID or it will be generated automatically. Region schema validation require the Region ID is string type, but there is no testcase to cover this.

CURL
=====================================================================
- create region,
curl -g -i -X POST http://127.0.0.1:35357/v3/regions -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: 9b7866d88de2408381549e9af55b0c07" -d '{"region": {"enabled": true, "id": 1234}}'

{"error": {"message": "Invalid input for field 'id'. The value is '1234'.", "code": 400, "title": "Bad Request"}}

- create endpoint,
curl -g -i -X POST http://127.0.0.1:35357/v3/endpoints -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: af9a74ea521045b2880e2a364a16b05a" -d '{"endpoint": {"url": "192.168.1.1:78", "interface": "public", "region": 7891, "enabled": true, "service_id": "ce08ac9579fc4de78d0ee17efeca530e"}}'

{"error": {"message": "Invalid input for field 'region'. The value is '7891'.", "code": 400, "title": "Bad Request"}}

    Add testcase to test invalid region id in request

    Regions use ID differently. The user can specify the ID or it will be
    generated automatically. So, there is schema validation that region ID
    should be the string type, these testcases test where region id could
    be passed in request body but not a string type.
