undercloud openstack-neutron-dhcp-agent is missing /dev/log:/dev/log and hence there are not logs for neutron-dhcp-agent.
This was fixed in RHOS1P13 via https://access.redhat.com/errata/RHBA-2019:0939 however the issue is still present on RHOSP14

https://bugzilla.redhat.com/show_bug.cgi?id=1707691 states a slightly newer puppet-tripleo-9.4.0-0.20190307172347.b5220a7.el7ost has the fix
