title: Github new Branch creation restriction
body: <p>I was wondering if there is anyway to restrict the branch creation in GitHub. I have 4-5 branches created for a repo and would like to maintain it that way. I have applied branch restriction rules on my master branch and hence the developers cannot merge into master but they can create their own branches . Is there a way i can restrict and force developers to use the other branches that are available and not create a new one ?</p>
  
  <p>Note: I use GITHUB Enterprise </p>
