Kerberos Authentication

nxc does support Kerberos authentication There is two option, directly using a password/hash or using a ticket and using the KRB5CCNAME env name to specify the ticket.

when using the option -k or--use-kcache, you need to specify the same hostname (FQDN) as the one from the kerberos ticket
