Add maven based server tests for Wildfly and Jetty (#10116)
This patch refactors the generic integration test war into
two jar dependencies and individual modules for different servers.
There is now a common approach for making configurations for the
remaining server tests still executed through an Ant build script.
* Integration tests moved from uitest to separate test modules
* Run TB4 tests with maven profile
* Remove old ant/ivy build scripts from uitest
* Add 'needs-ssh' test category for reconnection test
* Add default values for testing and validation builds
* Add placeholder build.xml with instructions to run Maven
