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.
The use of the module in the test project was removed earlier, and
eliminating the module permits simpler and more reliable builds as
it was not deployed.
The classes that were in uitest-common are now in uitest.
* 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
