Remove StorageSettings#legacy_disk_path from gitlab-ee
This will be one of the defining achievements of v1.1. It depends on almost every other issue in the milestone.
- the method StorageSettings#legacy_disk_path no longer exists
- no more repo storage paths in config/gitlab.yml.example
- omnibus-gitlab no longer renders storage paths into gitlab.yml
2019-05-27 This issue is blocked because we were forced to add the "rugged patches" in gitlab-ce, which gives users the option to partially roll back the Gitaly migration project to mitigate performance problems. #1690
