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
