gitlab保护分支设置

版本：gitlab10.2.2
一旦设置master分支被保护，除了管理员之外的任何用户都无法直接向master提交代码，只要提交代码就会报错

# git push -u origin master
Total 0 (delta 0), reused 0 (delta 0)
remote: GitLab: You are not allowed to push code to protected branches on this project.
To git@192.168.1.12:develpment/myproject-test.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@192.168.1.12:develpment/myproject-test.git'
