Statusplattform NAIS (K8s) Operator

This application is a webserver which leverages the Rust ecosystem's kube-rs to act as a K8s operator inside the NAIS clusters. At time of writing, it:

1. It reactively receives events on EndpointSlices by the K8s API
2. Ignores all events on EndpointSlice(s) we can't map to a Service owned by a NAIS Application
3. It checks if both (a) it contains pod IPs and (b) a minimum of 1x of them show 'Ready' readiness status
4. Send HTTP request w/NAIS app's readiness status to the statusplattform backend
