[devEx] Look into using argparse mutual-exclusion for --hub-name || --login scenarios

[digimaun]

• We should look into argparse mutual exclusion, to lean on argparse to improve usage/description devEx for --hub-name or --login usage.
  • https://docs.python.org/3/library/argparse.html#mutual-exclusion
• We need to see if there is any support for this in CLI core or Knack
  • If not, and if evaluation is deemed useful - consider building it out and integrating or informing the CLI core team on the need
