  Log Message:
  -----------
  Replace Cobertura with JaCoCo

This allows us to run unit tests once only, either with coverage
(-Dcoverage) or without.  I can't find a way to run tests exactly once
with Cobertura.  If surefire is configured to skip tests, Cobertura
won't run them either, and I can't find a way to generate a Cobertura
report on its own.

JaCoCo is configured to enforce coverage ratios, initially just for
zanata-war.
