Alexander Bokovoy 0022bd70d9 ipa-kdb: add PAC_ATTRIBUTES_INFO PAC buffer support 
PAC_ATTRIBUTES_INFO PAC buffer allows both client and KDC to tell
whether a PAC structure was requested by the client or it was provided
by the KDC implicitly. Kerberos service then can continue processing or
deny access in case client explicitly requested to operate without PAC.

Fixes: https://pagure.io/freeipa/issue/9031
