Allow to specify Kerberos authz data type per user

Browse Source 
Like for services setting the ipaKrbAuthzData attribute on a user object will
allow us to control exactly what authz data is allowed for that user.
Setting NONE would allow no authz data, while setting MS-PAC would allow only
Active Directory compatible data.
