Combination of Cilium Golang Envoy Filter and TCP tunnel to build Visual Studio Bridge To Kubernetes.

Why rebuild Bridge To Kubernetes?

The current version of Bridge To Kubernetes has some limitations, for example:

1. Can't have multiple pods behind a k8s service.
2. Can't have multiple container in a pod.
3. Can't have TLS between pods.

And these limitations can solved by the help of CNI.
