GitCAS::Open: allow specifying the log-level for failure

This method returns a GitCASPtr allowing the caller to handle
failure gracefully. Therefore, logging should be at most at level
Warning as it is up to the caller to provide the fatal error message.
Moreover, it can be at lower level in cases where failure to open
that git cas is not an unexpected event, e.g., when looking for a
blob in local mirrors first.
