build: add remote debugging with delve (#10587)
## Description

This is a feat and adds functionality for a developer to remote-debug a testnet node. This is made possible with `delve` remote debugging.

I received some help from here: https://kupczynski.info/2020/05/17/remote-debug-go-code.html

Also, @creachadair I made a tiny modification in the testnet file generation. I removed the `localnet` folder and simply let the `testnet init-files` to use the default `.testnets`, since this is also being `.gitignore`d in the repo, and we don't usually want these files in the main repo.

Let me know if there are any implications to your update that you made a few days ago.
