Run tests parallel to reduce execution time

Description

It would be nice if the integration tests could run simultaneous, at least the jetty, tomcat and undertow ones. Karaf ones use to much different ports.
For this it's needed to run Pax-Web with dynamic port and to get the port of the running server.

A first draft can be found in the tests_with_dynamic_port branch.
Some tests still fail.
Especially the https ones, but also others where a restart of the container is required.
