[Feature Request] Set proxy for internal full node or light client.

[yangby-cryptape]

Due to the poor Internet in some countries, both the internal full node and the internal light client are really slow with the default configuration.

So, I used the parameter --proxy-server="socks5://localhost:8888" to start Neuron.
It's a common parameter for all Applications based on Electron.

But I found it didn't work for the internal node or the internal light client, it only worked for the Neuron itself. Because I only found logs to query github.com and githubassets.com from my proxy server.

As the developers of Neuron said in #3098:

Self-hosted Light client is not allowed to be connected to Neuron

I think an official setting for set proxy for the internal node and the internal light client is required.
