Using --enable-all on the CLI pulls in some UDN functionality and has problems as reported in an internal slack thread (see link in comments)

1.oc netobserv flows --enable_all --peer_ip=w.x.y.z --get-subnets
2.  curl to test pod
3.

No traffic reported in CLI

Traffic is reported.

--enable-all is what is breaking things here.  It triggers ENABLE_UDN_MAPPING true.   Proposed solution is to remove UDN from --enable-all for 1.8 since it is an unsupported feature.
