consider shading the org.tomcat classes

[jorgheymans]

I ran into an issue with a spring-boot enabled grpc server and TLS, using netty-tcnative-boringssl-static:1.1.33.Fork24.

Basically the problem was that my project included the spring-boot-starter-web dependency, which brings in spring-boot-starter-tomcat, which depends on tomcat-embed-core. And this jar contains the same tomcat/jni classes used in openssl-dynamic, causing things to break.

This is a duplicate of #136.

We have re-namespaced netty-tcnative into a different package on the master branch. This change will take effect in netty-tcnative-2.0.0 and the next release of Netty should depend upon this new netty-tcnative.
