Move undertow jwa and servlet test under react repository

As we have discussed https://github.com/Atmosphere/react/issues/30, I've moved some test projects to react from [wes-servlet3-test](https://github.com/flowersinthesand/wes-servlet3-test/) and [wes-jwa1-test](https://github.com/flowersinthesand/wes-jwa1-test/).

But I could only move undertow tests. Here are issues.

* glassfish and tomcat artifacts have the collision with javax-websocket-server-impl artifact from org.eclipse.jetty.websocket group. It seems that the artifact scan classpath and do something and it brings the collision. I have no idea.
* tomcat 7 and tomcat 8 share the same package so they bring the confusion in the classpath. The same issue applies to jetty 8 and 9 and glassfish 3 and 4. Do you have any idea?
