Support for Tor Network in CKB

[eval-exec]

Feature Request

Is your feature request related to a problem? Please describe.

Bitcoin supports the Tor network. I believe CKB should support it as well.

Describe the solution you'd like

Bitcoin's implementation includes starting/connecting a tor server and using the Tor server's control socket API to create an onion service. Similarly, I propose adding flags to CKB such as -proxy=ip:port (need #4473) , -onion=ip:port, -onlynet=onion, -torcontrol=, and -torpassword.

I am considering the following approach like Bitcoin:

1. Start a Tor server that listens on port 9050. (Or enable tor's control socket API on 9051, then let CKB use the tor socket API tor create onion service self)
2. Run CKB using a proxy to operate behind the Tor network: ./ckb run --proxy=127.0.0.1:9050.

Describe alternatives you've considered

There is a Tor implementation in Rust called arti, but I am concerned that it may not be production-ready.
