Traffic Split

[mabombo]

Is your feature request related to a problem? Please describe.
We have the follow situation:
Our platform is multi pods services applications. View Image
We need to split traffic using app version (ex app label). When a user connect to the ingress, he is routed in version 1 or version2 on the first app based a criterial (header, %, etc etc)
From here, if user matches V1, the traffic is routed on all app version V1 inside kubernetes. (He use always v1 for all other Microservices).
In istio I use sourcelabel to achieve this. There is a easy way to implement the same routing with Nginx Mesh?
