Add templates Cmake + SonarQube Jenkins plugin

New templates gerrit-cmake-sonarqube and github-cmake-sonarqube
use the SonarQube Jenkins plug-in to analyze CXX code and publish
the results.  Modeled after the generic gerrit/github-sonar templates.
The new templates lift the limitations of the existing templates
gerrit/github-cmake-sonar which download and install a Sonar scanner,
and cannot report unit-test code coverage statistics.
