=> in theory the protocol does not allow to expire a lease before its
valid lifetime. So:
 - you can use the REST API to delete the lease
 - you can impersonate the client and release the lease
 - (more subtle) you can impersonate the client and renew the lease with
   a shorter valid lifetime (Kea does not prevent this)...

Another idea is to use the way Kea recognizes a client in particular
behind a relay with option 82.
