#146 Implement automated coverage tools

closes #146 implement automated coverage tool

Jacoco has been added

Coverall has been added to the GitHub workflow, to be used in PRs
Some Steps are needed to activate Coverall:

• 1. Sign up to Coveralls.io on their website using the Repo owner
• 2. On the Coverall website navigate to settings and Activate "leave comments?" and set them to detailed, bevor saving the changes. (Once signed up the link to the settings will be https://coveralls.io/github/devonfw/IDEasy/settings )
• 3. The coverall bot needs to be added to the repo, with write permissions (https://github.com/coveralls)

(Documentation can also be found on the Coveralls docu page )

I was able to skip step 1. and complete step 2. (as I was allowed to change settings in coverall for defonfw/ideasy)

... and complete step 2. (as I was allowed to change settings in coverall for defonfw/ideasy)

I think this setting can be changed by anyone on the web. Can we restrict this?

The settings can be changed by anyone within the Devonfw Github Group, but i can look into restricting it further

Looks good.

@moritzLanger Thanks for creating the PR. Looks all great. 👍
Also you used the latest version of the plugin what is always a best-practice

For the record: I did not grant "Write permissions" to coveralls as reading the documentation I found out that read access is sufficient. We will see if all works out or not.

one last thing @moritzLanger
IMHO you forgot to add the badge for coveralls to our README in this PR.
Can you afterwards create a new PR for that.

I just did it myself. Done.
