    Add is_admin to safe fields list for notifications

    We encountered bug 2037312 in unit tests when attempting to get this
    change rolled out. Heat apparently will attempt to set is_admin using
    policy logic if it's not passed in for a new context; this breaks as the
    context we are requested doesn't have all the needed information to
    exercise the policy logic.

    is_admin is just a bool; it's not sensitive; easiest route forward is to
    add it to the safe list
