Remove codeclimate and adopt SonarQube Cloud instead

[kwin]

Codeclimate.com does no longer provide free accounts (https://codeclimate.com/blog/code-climate-quality-is-now-qlty-software) for open source. OTOH https://www.sonarsource.com/plans-and-pricing/sonarcloud/ provides a free account for public repos and is easy to adopt. That allows also to capture coverage with Jacoco and upload to SonarQube Cloud instead (and get rid of codecov as well).

I removed the mandatory status check for codeclimate from the master branch protection rules (https://github.com/Adobe-Consulting-Services/acs-aem-commons/settings/branch_protection_rules/1307826) as it is no longer working.

@davidjgonzalez Can you onboard this repo in https://sonarcloud.io/projects/create (only organization owners can do that, https://docs.sonarsource.com/sonarqube-cloud/getting-started/github#set-up-your-organization).

Update: I see an empty project already here: https://sonarcloud.io/project/configuration?id=Adobe-Consulting-Services_acs-aem-commons. Can you setup a token and add as secret to this repo to be able to automatically analyse with the CI build.
