EpollTransport: support extended keepalive parameters TCP_KEEPIDLE, TCP_KEEPCNT and TCP_KEEPINTVL

Builds on #5183. This work has not made it into master, so I'm catching up on that.

I hope I've ported it correctly given the refactoring of the TCPSSLOptions / TCPConfig.

For motivation, see #5163 and #5183 and #5970

I am wondering for the new config to potentially have an Option object to be more extensible than what we have now.

@ivu-mawi I have introduced generic TCP option, can you rebase on master

Seems good! I'll gladly rebase when I get the chance, which will be next week only I'm afraid.

I'm trying to verify locally that it actually works. But I can't seem to get packet capturing to work in WSL (Windows subsystem for linux), and that's the only Linux I have access to at the moment. :(

I'll give up the test. Code is ready, I'll mark it ready.
