Enhancement required for toggleviyarules.py

[tomstarr]

Currently toggleviyarules.py works as it should, however, it's been noted that the disabling of some OOTB rules applied to AuthenticatedUsers can impact system functionality, as the system account 'sasapp' may be reliant upon this umbrella rule for receiving it's access.

toggleviyarules.py should be updated with either:

• a check of the principal (or principalType for "authenticatedUsers") and if "authenticatedUsers" is encountered, then a copy of the rule being disabled should be created, with the same permissions/rights, for the account 'sasapp'.
• an optional input argument to set the script to create new copies of any rules being disabled for the account 'sasapp'.

@gerrynelson63, I'll aim to work on this issue in the next week or so (it's ultimately to address https://gitlab.sas.com/snztst/viyaauthmodel/-/issues/1 ), however, if you have time and inclination to look into this ahead of then, please be my guest.

Updated toggleviyarules.py file has now be finalised, ready to be pushed and merged on 02AUG.
