/etc/resolv.conf and /etc/dhcp/dhclient.conf are not updated on new shards

Project Member Reported by shuqianz@chromium.org, Aug 11 2017 
8 Ganeti servers were provisioned into shards recently. However, puppet failed to update the /etc/resolv.conf and /etc/dhcp/dhclient.conf files on the new servers. I manually update 2 of them. Then I find that it is a puppet bug. The 8 servers are:
chromeos-server33.cbf   -->  the files are manually updated
chromeos-server35.cbf   -->  the files are manually updated
chromeos-server37.cbf
chromeos-server40.cbf
chromeos-server52.cbf
chromeos-server118.mtv
chromeos-server119.mtv
chromeos-server120.mtv

The dhclient.conf.head file is not updated on the servers, e.g. chromeos-server37.cbf:

# $Id: //depot/google3/googledata/corp/puppet/goobuntu/common/modules/network/templates/dhclient/dhclient.conf.erb#10 $
option tzName code 101 = text;

timeout 30;
backoff-cutoff 60;

# After b/17372393, we no longer get NTP servers from DHCP. This is intentional
# as the NTP DHCP client hook does not detect config updates properly, we are
# setting the same values in /etc/ntp.conf as the DHCP servers and
# corp-platforms is on the  notification list for the NTP server owners should
# there be service changes.

Cherry pick the fix CL, rerun puppet on chromeos-server37.cbf and have the following run error:

Error: /usr/sbin/goobuntu-config -u set 'dhclient_conf' 'yes' returned 201 instead of one of [0]
Error: /Stage[main]/Dhclient::Config/Goobuntu::Knob[dhclient_conf]/Exec[set Goobuntu knob dhclient_conf]/returns: change from notrun to 0 failed: /usr/sbin/goobuntu-config -u set 'dhclient_conf' 'yes' returned 201 instead of one of [0]
