Removing unnecessary runtime dependency of core: spotbugs-annotations

[akatona84]

Summary

1. Why: spotbugs-annotation is not used, originally was added as findbugs but at wrong scope I believe, but now it's not used at all
2. What: removing the unused dependency, cleaner dependency tree and not leaking as transitive at other projects (at Strimzi for example)

Expected Behavior

spotbugs-annotation not appearing in the runtime dependencies any more

Actual Behavior

spotbugs-annotation is in the runtime dependencies of cruise control

Steps to Reproduce

1. run ./gradlew :cruise-control:dependencies
2. check the output

Known Workarounds

Explicit exclusion is required in projects using the Cruise Control dependency.
