Support for upstream's disabling two-factor for specified providers
Summary
For GitLab 12.3, a new options is added to gitlab.yml for specifying a list of oauth providers that are exempt from two-factor auth. See CE MR: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/31996 Omnibus MR: gitlab-org/omnibus-gitlab!3543 (merged)
Documentation: https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/integration/omniauth.md#bypassing-two-factor-authentication
This config options should also be ported here into the charts.
The setting in gitlab.yml is:
omniauth:
allow_bypass_two_factor: ['twitter', 'google_oauth2']
