Integrate maven-dependency-plugin

[AmailP]

I would suggest to integrate the maven-dependency-plugin in CI and check that no warnings are emitted.

This is the output of an mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.1:analyze-only command on the current repo:

I would suggest to also add the analyze-dep-mgt and the analyze-duplicate targets.
