Fix Gitaly clone failure by making clone depth configurable

What does this merge request do and why?

Fix Gitaly clone failure caused by default clone depth being set to 1. Before Move binary compilation steps to shared script (!4316 - merged), Gitaly was cloned fully, but the shared clone_repository function added a default depth of 1. This caused compile:*:gitaly jobs to fail because the commit was missing in the shallow clone. This change makes clone depth configurable so Gitaly can be cloned fully.
