Add kubernetes support

[zimny]

The task is to create a variation open telemetry deployment and deploy it to kubernetes.

• The deployment should use the open telemetry collector k8s operator to deploy collector.

• There should be all scripting (makefile? look at https://github.com/nearform/k8s-kurated-addons/ for ideas) needed to deploy kind cluster.

• Front-end application should be deployed on a simple ngnix server that will be deployed on the same cluster.

• Back-end deployed as a simple kubernetes workload (pod/deployment/service?) or knative application.

• Images must be available in a public registry.

• There should be an option to deploy collector as a single instance or a two-layered approach that will enable tail based sampling (traces).

• Collector should send traces into jeager as a backend.

• All relevant properties should be exposed as environment variables.
