As currently used one is plagued with CVEs etc.
As long as we are stuck on Java8, we cannot move forward
with Jetty, as Jetty 10.x (that is drop in replacement)
is Java 11.
Even test is skipped by `@Disabled` annotation
newer surefire schedule it for execution.
When tests are missing in TestSuiteOrdering
are executed as one of first tests in unpredictable order.
Update Jetty to latest 9.4.50, last Java 8 capable version. Apply API changes and also remove jetty-servlet as ITs does NOT use servlet aspect of Jetty HTTP server.. This will simplify our lives in future, to make jump to later versions (that are Java 11+). Also, drop jetty-servlet as test do not use any servlet aspect.
