RFR 8131051: KDC might issue a renewable ticket even if not requested

Ping again.

Basically, Java currently requires the renewable flag of a ticket to be 
identical to the renewable flag in the request, and thus rejects the 
following legal case:

  - Client requests for a non-renewable ticket with a lifetime of 2 days

  - KDC thinks 2 days is too long, instead, it issues a ticket with a 
lifetime of 10 hours, but makes it renewable with 2 days

Thanks
