    Redelegation is valid if each subsequent trust in a chain passes 'not more'
    permissions than being redelegated.

    Trust constraints are:
     * roles - set of roles trusted by trustor
     * expiration_time
     * allow_redelegation - a flag
     * redelegation_count - decreasing value restricting length of trust chain
     * remaining_uses - DISALLOWED when allow_redelegation == True

    Trust becomes invalid in case:
     * trust roles were revoked from trustor
     * one of the users in the delegation chain was disabled or deleted
