Testing is in different modules for OSGI development

    * site-deploy hook gets the target as argument

    * LogUtil works by classes, not names. TestUtil.assertStreamEquals

    * assertStreamEquals is static

    * Logutil has warning and info, TestBase gives more precise error in autowiring failure

    * rearranged poms so it builds without tricks

    * different test modules, using src/main

    * konveyor resources are in .konveyor

new functionalities
