keep perfdata of retired hosts

When we want to see the historical hardware-usage of an application, that was moved to another host, currenlty I loose all the historical perfdata, when I remove the old host of that application.
otherwise, I must keep the old host and keep it constantly under downtime, but then checkMK always try to reach the host that is already offline.

for that usecase it would be greate if a host could be set to a "retired" state, so it is no longer actively monitored, but the perfdata is still stored in the system.
