CI coverage

Brings coverage estimation to the QA jobs:

• The coverage doesn't take into account the lines of code in:
  • Modules/*/*/test
  • Modules/ThirdParty
  • Examples
• The coverage build is now in Debug
• Some tests have been modified to take less time (running the tests on this build is a lot slower)
• The QA jobs are disabled if no Sonar token is present

Although empty on SonarQube dashboard, the coverage after merging this branch should be around 59%
