permissive policies should be excluded

[ellarabi]

policies document:

(1) customers with "gold" membership can book a flight with any passengers number regardless of their frequent flyer points
(2) customers with "regular" membership cannot book a flight with more than three passengers unless they own ...
(3) customers with "silver" membership cannot book a flight with more than seven passengers
(4) ...

attaching also oas.json, book_reservation.json and the generated guard code.

book_reservation.json
guard_gold_membership_unlimited_booking.py
oas.json

we should probably skip (put aside) permissive policies like (1) since they are not the case we handle with toolguard

right now the guard throws exception for any customer that is not "gold"
