[FEA]: ci/scripts/gitutils.py::_run_cmd should allow explicitly setting shell=True

[dagardner-nv]

Is this a new feature, an improvement, or a change to existing functionality?

Improvement

How would you describe the priority of this feature request

Low (would be nice)

Please provide a clear description of problem this feature solves

Currently the shell argument is determined based upon shell = len(args) <= 0 however there are times when a caller may explicitly need shell to be True, such as using the | pipe operator.

Describe your ideal solution

Expose shell as a function argument or always set it to True
