Add nagle's algorithm

[shoham-b]

Add the possibility to use [https://en.wikipedia.org/wiki/Nagle%27s_algorithm?wprov=sfla1](nagle's algorithm).

This should come with the possibility of turning off the delayed ack due to collision between the two.

So to be honest last time i actually worked on TCP implementation was almost year ago and i left it then in a 'good enough for now' state with the intntion of improving it over time. Of course i never had chance to get back to it again. This definitely should be added to TODO list and of course if you could propose the code change to implement it that would be welcomed too. Thank you.
