add support for breaking the build if at least one pseudo-tested exists

[monperrus]

We want to break the build if at least one pseudo-tested method exists.

Today, to break the build in CI based on Descartes, we need to write additional imperative code that analyzes the JSON file produced by Descartes.

It would be great to be able to simplify this, by configuring the pom.xml and break the build if at least one pseudo-tested method exists.

This would be similar what jacoco is doing to break the build based on coverage info, see https://www.jacoco.org/jacoco/trunk/doc/check-mojo.html

And its usage in Spoon: https://github.com/INRIA/spoon/pull/3641/files
