 Is there some way to force all leases under dhcpd to perform lease
 renewal routine?

Even if the dhcpd implements INFORM, most clients won't.

In practice, if you want the clients to update before their existing
lease is due for renewal, you generally have to go around to the
clients individually.

Or plan ahead. If you know you will be changing some lease options you
should set the lease time down to something small at least
$(current_lease_period) seconds ahead of time. Then you can be fairly
certain that all systems will get a new lease within
$(new_lease_period) seconds of you change. Afterwards you can increase
the lease period back up. Of course, this assumes you were not handing
out infinite lease periods.

Shorten the lease time? See dhcpd.conf(5), max-lease-time  default-lease-time 
parameters.
