[Kea-users] Enable lease affinity with MySQL backend

Has anyone been able to get lease affinity to work with a MySQL backend?

I am using 1.3 for dhcpv4 and dhcpv6, and whenever a client issues a
release, the entry is immediately removed from the database.  I would like
the lease to be retained at least until it expires so that the customer
will get the same address and prefix when their CPE comes back up.  Without
it, they get a new delegated prefix and public address any time their
equipment reboots, which causes their whole network to renumber.

I don't want to go through the trouble of creating a host for each
customer, I just want them to keep the address they get as long as they
renew it from time to time.

I can see lots of references to a remove_lease variable, but I can't seem
to find the configuration variable to set it to false.
