feat: tooltip plugin to show series data in tooltip (#6194)

* feat: tooltip plugin to show series data in tooltip

* feat: send anomaly function as last function

* feat: default z_score_threshold to 3

* fix: anomaly function not applied on initial load

* feat: maintain select alert type on reload

* feat: maintain select alert type on reload

* chore: update events to handle anomaly alert interactions
