Get the other metrics from Kubernetes components

[ecooke-macu]

Description

There's a lot of other metrics that are exposed from the API server that we need to get. Probably from the other components as well.

Acceptance Criteria

Ability to bring in all metrics from all components with an exclusion list like the Prometheus agent. Reasoning for the exclusion, we don't want the .*_bucket/histograms since that is a massive amount of data we don't need.

Describe Alternatives

Scraping the endpoints using the agent. This works for the API server because it's publicly accessible using a token. However, the other components hardened against the CIS benchmark must listen on 127.0.0.1 and not the exposed to the network through the node's IP or 0.0.0.0. So that doesn't work for things like the kube scheduler/controller/kubelet.
