Issue:
Support create network EnableIPv6 and Labels options 
Check the remote API:
https://docs.docker.com/engine/reference/api/docker_remote_api_v1.23/#create-a-network

There are two missing JSON parameters:
```
EnableIPv6 - Enable IPv6 on the network
Labels - Labels to set on the network, specified as a map: {"key":"value" [,"key2":"value2"]}
```
