Click Refactor - Traceback doesn't show on Ctrl+C

[jsonvillanueva]

During the times of Argparse, Ctrl+C would show the traceback. Click has its own exception handling which conflicts with how Argparse would've handled this previously. Instead it just shows Aborted! prior to ending program execution.

The solution to this should be on this page: https://click.palletsprojects.com/en/7.x/exceptions/?highlight=aborted#what-if-i-don-t-want-that but needs to consider our entry point.

Is there a case where we actually want to have the full traceback -- does this not work as intended as-is? Closing this for now (but we can reopen in case the issue still exists and can be specified more precisely).
