Add support for tcp keepalive

[irevoire]

Hey, we have a lot of issues with this crate disconnecting from the network and making the whole process crash, basically.
It's strange because we didn't have any issues at the time when we were using https://docs.rs/zookeeper-client/latest/zookeeper_client/
Do you know what could be the culprit?
We're running with the exact same zookeeper version.

I thought adding support for tcp-keepalive could maybe help, but I doubt it.
Fix #92

Also, since we establishes the connection straight away in the new and don't use a builder or something, I had to introduce a new parameter in the new function which is a breaking change 🥺

Hi @irevoire, thank you for the work in this PR, huge help!

TBH I have no idea what could be the issue, I'm not familiar with zookeeper_client. But I'm curious why have you moved away from it to this crate?

We wanted a sync client and that's the only one available I think 🤔

No problems with the break, I think we can bump another "major" minor version here. Or creating another constructor with keepalive or more settings (like a config struct, I'm not sure how Rusty is this)?

I think the most common thing is to have a builder, but tbh, I won't have the time to do it
