Update JAPICMP on a module by module basis

We are using japicmp-maven-plugin to check public API changes between different versions. This is a way for us to see if we have any incompatible changes between releases.

Currently, we have JAPICMP configuration (what to include in the check and what not, etc.) in the parent module.

But each module should test it's own compatibility - however the compatible version should likely be defined in the root pom.
