Proxy settings for Docker daemon

[Eyre-S]

Describe the feature

Ability to set proxy for Docker daemon.
This is normally be done by editing /etc/docker/daemon.json

Use cases

In some country and regions, the connection to docker-hub (and github) is banned by govenment or ISP (or the speed is very slow), makes updates associated to docker is almost unavailable.

By using a proxy, this problem will be solved.

Current workarounds

There is a solution by using an external network gateway which can route every connections to proxy, and set gateway ip to that external gateway.

But the problem is, it will affects local network related services, and IPv6 stack is fully unsupported (due to IPv6 external gateway with ISP dynamic IP is not possible).

Before, I can write /etc/docker/daemon.json manually using Supervised installation. But when Supervised has deprecated, I can only hope it can be supported by HAOS.

Anything else?

Here is also another use case for having an under layer for proxy.
I'm using HAOS in my school to monitor my DataCenters. As we are public entity, we have installed some network protection. The only way to get HAOS and addon update is thru internet and so thru the proxy.

I've tried to set the proxy on supervisor at nmcli level, but container just don't care about this low level setting.
