apache-frontend: Drop _ from domain name (!320) · Merge requests · nexedi / slapos · GitLab

Merged Łukasz Nowak requested to merge luke/slapos:fix/apache-frontend-underscore into master Apr 23, 2018

_ (underscore) is not supported by apache as domain name (https://bugzilla.redhat.com/show_bug.cgi?id=1410130), so avoid using it.
