.SYNOPSIS
Invokes an external utility, ensuring successful execution.

.DESCRIPTION
Invokes an external utility (program) and, if the utility indicates failure by 
way of a nonzero exit code, throws a script-terminating error.

* Pass the command the way you would execute the command directly.
* Do NOT use & as the first argument if the executable name is not a literal.

.EXAMPLE
Invoke-Utility git push

Executes `git push` and throws a script-terminating error if the exit code
is nonzero.
