At present this template appears to be designed to never interfere with
other jobs in your CI YML. This is true for all cases except the global
`before_script` which will cause other jobs in your `.gitlab-ci.yml` to
possibly end up in the wrong directory. This was specifically important
for a use case where a project was using terraform and ansible in
https://gitlab.com/gitlab-org/quality/gitlab-environment-toolkit . The
simplest solution appears to be to just inline the `cd ${TF_ROOT}`. We
also considered defining another hidden job that is extended by all the
other jobs here but the indirection didn't seem worth it for a single
step.
