Subject: [PATCH 1/5] BAEL-20655 Which sub-modules aren't being built?

- Added several missing modules in the main pom.xml
- Fixed the modules list for all the profiles
- Commented several test cases so that all modules can run and be included in the pom.xml
- Moved child modules from main pom to parent modules pom
