title: How to delete sonarqube branches in database
body: <p>I have a sonar dashboard which has projects on branch level. Most of the Sonar branches(projects) are not used now.</p>
  
  <p>I have written a script to clean-up the branches in sonar which works fine but the branch details in sonar database were never removed.</p>
  
  <p>Please let me know the best way to remove the deleted projects in sonar database as there branches are of a lot older releases and will never be analysed again</p>
