title: SonarLint displaying issues only in files changes
body: <p>I'm looking to improve the code base of the department I'm working and I want to do it in a incremental way.
  My idea is that I only want to be running SonarQube and SonarLint in the files that the developer is changing.
  In sonarqube we have:

  <p>Is there a way to do the same in SonarLint?</p>
  
  <p>With a code base with a big technical debt, if SonarLint is going to list the issues of all the current files and I only want to list the issues of the files that the user has changed.</p>
  
  <p>Let me know your thoughts or any other way to achieve something similar</p>
