Fix the junit tests, bump sleep for bind issues

1) Merged the changes from Szczepan for fixing the Junit tests.
Previously JunitAll ran the integration tests and ran over 4 hours.
2) Szczepan removed redundant sourceSets, moved common configurations

3) Created aggregated reports for junitAll verified the coverage was

4) Noticed few bind exceptions on 2 ms sleep, so bumped them to 5 ms.
