I can't get Atlantis to work with our private Gitlab server when the Gitlab is installed under a relative URL, like this: https://my.company.com/base_path.

I provide the --gitlab_hostname: "my.company.com/base_path/" flag when starting Atlantis.

But got the following when creating a new PR:

[EROR] server: Error parsing webhook: expected clone url to have path "/repo_path/Repo.git" but had "/base_path/repo_path/Repo.git

This error seem to be similar one this Bitbucket case #508
