Remove setting ip forwarding via openshift profile

Browse source 
With openshift/machine-config-operator#3676 we
removed globally setting ip forwarding in MCO. We should not be setting
it in the default profile for OpenShift. We now set it on a per
interface basis as needed. However, by setting proc/sys/net/ipv4/forward
rather than (forwarding) it will reset all the values:

"This variable is special, its change resets all configuration
parameters to their default state (RFC1122 for hosts, RFC1812
for routers)"

We suspect this causes upgrade to fail. NTO sets this to 1, which then
resets all the per interface config that OVNK wrote. Then during upgrade
when there is a tuned profile change, the config change is rolled back
so forward is 0, and now there is no connectivity to kapi and upgrade
fails.
