Grant permissions related to booking/reservations to circulators and admins

This should make for a better out-of-the-box experience for Evergreen adopters.
The permissions in the upgrade script are outside of the transaction to avoid
rolling back the entire upgrade if a site has already assigned these
permissions.

TODO: Document the new permissions as part of the 1.6.1 release notes so
that sites can alter the upgrade script according to their desires if they
don't like the defaults.
