ingress manifest remove static namespace entry

[jameskochubasas]

The generated ingress manifest contains a reference to the static namespace (verse other manifest don't give command flexibility) requiring the user to manually modify vs using the command option (-n or --namespace) to dynamically change based on K8S cluster namespace.

Recommend removing that property inside the generated file so the recommended output commands work:
kubectl -n jakoch apply -f builds/full/manifests/kubernetes/ingress/sas-viya.yml &&
kubectl -n sas-viya apply -f builds/full/manifests/kubernetes/configmaps &&
kubectl -n sas-viya apply -f builds/full/manifests/kubernetes/secrets &&
kubectl -n sas-viya apply -f builds/full/manifests/kubernetes/services &&
kubectl -n sas-viya apply -f builds/full/manifests/kubernetes/deployments

If you don't remove that option and want to change namespace on command, it fails:
kubectl -n jakoch apply -f ingress/sas-viya.yml --namespace=ssa-viya
error: the namespace from the provided object "sas-viya" does not match the namespace "ssa-viya". You must pass '--namespace=sas-viya' to perform this operation.
