Gateway API State Metrics

TLDR

Inspired by https://github.com/kubernetes/kube-state-metrics, this is a proposal for a prometheus metrics exporter. The exporter will export metrics solely for Gateway API resources. The exporter will watch the kubernetes API server for Gateway API resources and convert the contents of the resources into metrics with labels and values.

By providing a standard set of metrics around Gateway API resources it will allow further standardization and sharing of things like:
