[FIXED JENKINS-9691] Boldify names of executed mojos for Freestyle and

Maven2/3 jobs using Maven3 in console output.
With Maven3 the output format for mojos has changed:
- Add a new Maven3MojoNote and use it in MavenConsoleAnnotator.
- This is sufficient for Freestyle jobs running Maven2 or 3 and Maven2/3
  jobs running Maven 2.
- Maven2/3 jobs running Maven 3 are using ExecutionEventLogger for
  printing start of mojo execution to console.
