Allow OAuth SSL verification to be disabled when importing from GitHub
Close https://gitlab.com/gitlab-org/gitlab-ee/issues/457
The SSL verification should be disabled if the GitHub Enterprise use a self signed certificate. Even disabling this on GitLab, the Git client installed in the server will perform the verification and stop the process if it is unknown. So, we need to disable Git SSL verification in the server hosting GitLab
with the following command:
$ git config --global http.sslVerify false
