Adding submodule jetty-servlet of Eclipse Jetty into the openctest framework

Brief changelog

• Modified the submodule jetty-servletof and forked own ctest-jetty repository. Created two clean branches, ctest-logging and ctest-injection, in this repo, which can be used for values logging and injection.
