[Metrics UI] Anomaly Detection setup flow for Metrics

[phillipb]

Summary

Adds the ability to set up hosts and k8s anomaly detection jobs on the inventory screen, and adds endpoints and hooks for fetching anomalies associated with those jobs. The PR sets up an infra_ml directory that could become a shared directory with logs code in the future. There is a good amount of copying from logs taking place, and it would be good at some future date to refactor/dedupe some things. Fixes: #74808, #74807

Known issues

• You will need to update the source configuration and remove metrics-* from your index pattern to make this work. This should be fixed by [ML] Datafeed fails on missing indices, even with allow_no_indices set to true elasticsearch#62404.

We should replace all the npStart.http.fetch requests with useHTTPRequest hook (under public/hooks). There seems to be a lot of duplicate functionality and it will make it easier update later.

[phillipb]

@simianhacker switching to useHTTPRequest isn't really clean with the way the code is structured. useHTTPRequest is a hook with state, but these calls to npStart.http.fetch are expected to flow more procedurally. They chain together which makes it really hard to do via effects. For example, https://github.com/phillipb/kibana/blob/81bc98860447f6d6871108a751d50204c2fdc259/x-pack/plugins/infra/public/containers/ml/infra_ml_cleanup.tsx#L10. cleanUpAndSetUpModule which calls callStopDatafeeds and then calls deleteJobs and then calls, setUpModule and then calls getJobSummary. Cleaner and easier to write that without hooks.

Tested it with a RO user and Admin and everything works as expected. Good Job!
