Consider upgrading to latest netty 4.0.x.Final version
Description
For the next java driver (3.8.0?) minor version, we should consider upgrading the netty dependency from 4.0.56.Final to the latest 4.0 version. One reason in particular is that we found that newer versions of netty-tcnative do not work with 4.0.56.Final. To make life easier on users if upgrading to a newer version of netty enables using newer netty-tcnative versions, it will make using netty-tcnative more approachable.
