Remove unused config and override maven home and cache on CLI

[jonesbusy]

I don't think we need to change the mavenRewritePluginVersion at runtime. Can be just a constant on the Settings

But passing the --maven-home sounds more useful on environment that doesn't declare (M2_HOME or MAVEN_HOME)

Also use Pathinstead of using String for paths

Testing done

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue

Draft need to fix tests

This is ready for review. The last commit also ensure to have a predictable version of maven when running integration tests (in the future) and not rely on environment but surefire env vars
