By default, AppStack doesn't allow pod to pod communication across namespaces. When pod need to talk to another pod on different namespace, it require to go via the service layer / service cluster IP. This create a challenges for apps that require to communicate to pod directly when there not resides on the same namespace - example - any ingress controller - nginx ingress or F5's SPK.

Idea is to have some options to allow pod to talk directly to another pod across namespace.
