Use undici instead of http Agent

I propose to take a look into [undici](https://undici.nodejs.org/#/

Why Undici

[slvrtrn]

As of 0.2.x, we can utilize @clickhouse/client-common to create a new Node.js client implementation alongside the existing one (similarly to @clickhouse/client-web).

I guess "socket hang up" and, generally, how KeepAlive works are the main issues with the current version that uses just the standard library.

So, the main question is: is it possible to create a barebones example where undici will not fail with these "socket hang up" errors where the current implementation will? Cause the worst-case scenario will be that we'll have the same errors, but now with two different flavors of the library, which I would like to avoid.
