The lease state of 1 means "declined lease". A client declines the lease 
when it discovers that someone else is using the leased address.

Kea currently defines only three states for leases: "default" (or 
"active"), "declined" and "expired-reclaimed". The last state marks the 
leases that have expired and the server processed them during routine 
reclamation. In particular, a reclaimed lease has DDNS state cleared. 
Such a lease is available for new allocation.
