Use the same host key for all hosts on the cluster.

Unfortunately we don't administer that cluster and that is unlikely to
be allowed, I can ask! I was trying to find a workaround on the client
side though PuTTY may in fact negate any attempt.

In that case, here's a grim hack that will allow you to get round such
issues with the current state of PuTTY:

- On the Proxy panel, set "Proxy type" to Telnet and "Telnet command"
to the empty string.

- Set "Proxy hostname" and port to the real hostname and port you want
to connect to.

- On the "Session" panel, set the hostname and port to the name you
want the host key to be stored under.

What this does: the proxy setup creates a "null proxy" where a TCP
connection to one hostname is used as a proxy for a connection to
another hostname. The hostname/port you configure on the Session panel
get used to decide where the SSH host key is stored / looked up, but are
otherwise ignored, so they don't even have to correspond to a real
hostname.
