Set up a dummy Git username/email so that clone doesn't fail
When testing to clone different branches than master, the following error would occur:
=> Pulling docs/autodeploy-refactor of https://gitlab.com/gitlab-org/gitlab-ce.git
From https://gitlab.com/gitlab-org/gitlab-ce
* branch docs/autodeploy-refactor -> FETCH_HEAD
*** Please tell me who you are.
Run
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: unable to auto-detect email address (got 'root@runner-4e4528ca-project-1794617-concurrent-0.(none)')
