    [KYUUBI #6396] Add caching for KerberosAuthentication using ticketCache key
    
    This pull request fixes #6396
    
    By using a cache to store CachingKerberosAuthentication objects keyed by 
the ticket cache path, we ensure that each unique ticket cache path generates a 
distinct authentication object.
