title: Git deny users to create tags
body: <p>Here is a question about git repo management...</p>
  
  <p>Is it possible to configure git repo to allow TAG creation only for some users?
  And similar question for branch: is it possible to configure list of user, who are able to modify particular branch?</p>
  
  <p>The idea for all this config is: there is git repo with MANY developers, and we want to have a few stable branches and list of tags. And only senior developers will be able to modify those branches and create tags.
  All other developers still can create branches and so on. But if developer wants to promote his changes to one of stable branches, he must to contact senior person to ask him to make merge...</p>
  
  <p>thank you</p>
