Update sonar functionallity to handle 7.9.3 version

[sandinosanchez]

In 5.1 we are going to update sonarqube to 7.9.3 so all previous logic needs to be updated aswell. New functionallity to handle pr decorator and decompose old sonar class into the SonarCient to suport custom sonarqube instances.

[sandinosanchez]

Environment:

• jenkins-master:5.1-beta4
• infra-branch > develop
• pipeline-branch > develop
• sonarqube:2.2-beta1

Objective:

• Test the new version of sonarqube and verify that all the features(onPush sonar analysis, pr decorator) work as intended with embeded and custom sonarqube.

Pre conditions:

• GithubApp created and configured with sonar server(ping me for the configuration)
• Ghprbhook configured in jenkins
• Webhooks configured for carina-demo

Test scenario:

1. Run registerOrganization job
2. Run registerRepository job with carina-demo
3. Create a branch from master in your froked carina-demo
4. Modify a class with some unused fields(ping me for information about this one)
5. Create a pr from that branch to master

Expected results

2. onPush job executed successfully
3. sonar scanner results should be displayed in the pr > checks tabs
