Fix errors when generating javadoc for 3rd-party apps

Because of this bug in Open JDK 11:
https://bugs.openjdk.java.net/browse/JDK-8212233

The fix is to update the maven-javadoc-plugin version in
onos-dependencies via onos-base (bumped to v2).

This patch introduces further improvements to onos-dependencies such as:
- Profile that emulates CI release jobs (e.g., javadoc verification)
- Compile-time errorprone checks
