Add additional documentation regarding available jenkins slave images for Sonar scanning

[WadeBarnes]

The following Jenkins slave images are available in the Pathfinder OpenShift environment;

• jenkins-slave-base-rhel7
• jenkins-slave-bddstack
• jenkins-slave-nodejs
• jenkins-slave-nodejs6
• jenkins-slave-py3nodejs
• jenkins-slave-python-rhel7
• jenkins-slave-python3nodejs (created for Sonar scanning)
• jenkins-slave-sonar (created for Sonar scanning .net applications)
• jenkins-slave-zap (created for zap scanning)

These images are built off the sources found here; https://github.com/BCDevOps/openshift-components/tree/master/cicd

jenkins-slave-sonar is an image created for .net applications. Built from https://github.com/BCDevOps/openshift-components/blob/master/cicd/sonar/Dockerfile

Example using that image:

• The pipeline using it is here; https://github.com/bcgov/hets/blob/master/Jenkins/sonarqube/Jenkinsfile

Question:

• Can jenkins-slave-sonar be used in place of jenkins-slave-python3nodejs so there is just one image used for Sonar scanning.

Can jenkins-slave-sonar be used in place of jenkins-slave-python3nodejs so there is just one image used for Sonar scanning.
If the image also contains Python, sure why not. Right now I am not sure it does.
