* Add falco service to k8s install/update labels
Update the instructions for K8s RBAC installation to also create a
service that maps to port 8765 of the falco pod. This allows other
services to access the embedded webserver within falco.
Also clean up the set of labels to use a consistent app: falco-example,
role:security for each object.
* Cange K8s Audit Example to use falco daemonset
Change the K8s Audit Example instructions to use minikube in conjunction
with a falco daemonset running inside of minikube. (We're going to start
prebuilding kernel modules for recent minikube variants to make this
possible).
When running inside of minikube in conjunction with a service, you have
to go through some additional steps to find the ClusterIP associated
with the falco service and use that ip when configuring the k8s audit
webhook. Overall it's still a more self-contained set of instructions,
though.
