Support IPv6-only environment

[LittleWat]

Proposed change

support IPv6-only environment.

I'm facing the same error as How to setup juypterhub with ipv6 config on kubernets cluster - JupyterHub - Jupyter Community Forum

Alternative options

nothing

Who would use this feature?

IPv6 user

(Optional): Suggest a solution

It would be necessary to update NetworkPolicy, jupyterhub_config.py, etc...
