Prior to 8.0.28 Tomcat required the key store and trust store (if any) to be available directly on the filesystem, i.e. classpath: resources would not work. Tomcat 8.0.28 removed this limitation. This commit updates to Tomcat 8.0.28, updates the tests to verify the new Tomcat capability and removes the obsolete documentation of the restriction. Closes gh-4048
