[APM] Service maps - Fix missing ML status for services with jobs but…
Browse files Browse the repository at this point in the history
… no anomalies (elastic#68486)

* Closes elastic#68485 by:
  - use the ML plugin to query for all APM jobs
  - inspect the ml job groups to find all jobs related to a particular service
  - use the mlAnomalySearch client to get ml job buckets with the max anomaly score
  - query for the model_plot buckets to obtain actual/median values for the ML description
  - return the relevant ML job with the max anomaly score for a service
  - indicate to the user that no anomalies were found for a service with an ml job

* - Use the anomalyDetectorsProvider jobs API rather than the search endpoint directly
- Defines a specific return type for the ml jobs api
- Update the empty anomaly data message

* Code and types cleanup

* Return to using record result type on anomaly queries. These are the
same values used in the anomaly explorer and it includes actual &
typical values which greatly improve performance of the previous query.

* - If anomaly data is missing show a gray border around node

* - moved AnomalyDetection out of service map Contents into own component
