maven: Support parallel builds

See original GitHub issue

Running mvn with --threads 1C (i.e. one thread per core) produces the following warning:

[WARNING] *****************************************************************
[WARNING] * Your build is requesting parallel execution, but project      *
[WARNING] * contains the following plugin(s) that have goals not marked   *
[WARNING] * as @threadSafe to support parallel building.                  *

Let’s get rid of that and enable smooth parallel builds, shall we? I’m happy to take any pointers towards an implementation, but am not sure yet whether I can PR, depending on the complexity of the change.

@lorenzleutgeb I’ve decided to mark a plugin as threadSafe. The check-list from maven passed and I don’t see any issues besides “same output directory used by multiple modules” (which is the very unlikely situation and even if it is the case, then the client should disable parallel builds). Will release the change in version 3.2.0 this week.
