7.5. node sends kvno from its cached ktab, 0 for "don't have ktab"

8-10. collector checks:
<node hostname> = resolve from incoming IP
if not exists "libvirt/<node hostname>" principal
	add service principal "libvirt/<node hostname>"
get kvno_from_kdc for "libvirt/<node hostname>"
if kvno_from_kdc != kvno_from_node
	get keytab for "libvirt/<node hostname>"
	respond "TAB"
else
	respond "BYE"
