Consider using depth of 1 when automatically cloning a git repo

[teojgo]

This would make cloning much faster

[vkarak]

Agree with that, but you mean we should do that in the unit tests or in the osext utility?

[teojgo]

On osext we can do it using the opts. I was thinking when we use a git repo as the source of the code. On seconds thought though, in tests where we switch to a git branch as a subsequent command then the branch is not there since the depth does not cover it, unless we enrich the source syntax to include a branch and/or depth by itself.
