REPO-5271 Backport new structure to relaese/6.0.0 (#14)

- Simplify dependencies and standardise order
- README updated
- Green builds
- Changes to make Jars in enterprise war match
- Changes to make files in enterprise image match
- Added travis_wait 40 to the initial build as it can take 20 minutes to download artifacts
- Removed TAS tests from .travis.yml but not the code as TAS tests require Java 11 - Added in an empty test so the build runs on feature branches.
