Move Kong to infra deployment

Move Kong to infra deployment

If we keep Kong in ricplt and ricxapp spaces, when we deploy both
groups on the same k8s cluster, we will have two Kongs and they
overlap because both by default monitors all NSs.  In new version
of Docker, one will actually "kill" the other, leaving the ingresses
for the dead Kong without ingress controller.  Moving to ric-infra
we will only run it once and one Kong is deployed.
Also modified common template's ingress controller port number def.
Now there is only one port defined.
