Defining proxy (SOCKS/HTTP)

[tasooshi]

It should be possible to provide arguments for SOCKS or HTTP proxy, must be reflected both in the API and the CLI.

To consider: using both in parallel, for any protocol that has preferences on which one to use?

Moving to the future, requires multiple protocols (services) to be implemented.

Considering my recent experiments with socks and proxying, this would be extremely difficult to implement since there's no currently maintained (and working) socks library except for some fresh stuff for asyncio. Instead, user should be instructed how to use other tools for proxying. TBC
