title: Gitlab to Jenkins webhook with parameters
body: <p>I'm trying to build a job on my jenkins using Gitlab webhook when pushing into a specific branch.
  The only issue I have is that the jenkins job is parameterized. The parameter is the branch name.
  Is there an option to add the branch name (its a different branch every time) to the webhook so it will be inserted automatically into the parameter in the jenkins job parameter?</p>
  
  <p>Thanks</p>
