Resolve "Set the default values for the k8s-monitoring chart to receive and publish tracing data."

General MR

Summary

This MR sets a network policy that allows alloy to receive OTLP over gRPC or HTTP from any pod in-cluster. The network policy pulls port numbers from the k8s-monitoring subchart to make sure they're always in sync.

This MR also includes the fix necessary to resolve issues alloy had pushing metrics to prometheus.
