Remove or fix withReadTimeout

[ArtDu]

It doesn't do anything right now

It should set a read timeout for a request if I understand correctly what this ticket is about.

For request timeout we have requestTimeout, but read timeout isn't being used in code

The proper solution for this is to use https://github.com/netty/netty/blob/4.1/handler/src/main/java/io/netty/handler/timeout/ReadTimeoutHandler.java. It seems the option was added with that in mind, but the handler was not added.
