Ensure a git repo exists on disk and that it's up-to-date.

Clones the git repo specified by url to the path outPath. If the repo already exists on disk, then a pull is performed to update the repo instead.

The git repo is shallowly cloned by default. To make a complete clone, set options.depth to Infinity. If the git repo was previously cloned shallowly, it remains shallow.

When the operation is finished, callback is called. The first argument to callback is either null or an Error object if an error occurred.
