title: Add bulk of users in gitlab using gitlabapi
body: <p>I am able to add a single user using Gitlabapi but, I need to add many users so Is there any possibility to add bulk of users at a time to Gitlab project using Gitlabapi. And while creating users, role and the group should be assigned as well.
  I am using node.js for implementing this. Is there any library in node.js to do all these functionalities???</p>
  
  <p>I found one library(i.e, gitlab) in node.js but with that I can able to fetch users, projects and create projects but am not able to create users</p>
