bug #1012438 Additional work for bp v2-api-melange-integration - rename few attributes: op_state -> status additional_routes -> additional_host_routes prefix -> cidr - expand request body validation to indicate whether fields can be specified during create and or update. - add test cases to validate defaults, and input validation. - update db_base_plugin_v2 to generate gateway_ip for subnet and mac for port when unspecified. - validate that tenant-id is only specified in req by admin users - automatically set tenant-id based on request.context.tenant_id if needed - enable port tests in test_db_plugin.py Change-Id: If7f5101e4974a6ef93ff8a1d945f8642dd21b16e
