UI for anomaly detector configuration #270 && Optional HSR #273 (#278)

* Introduce anomaly analytic unit

* todo

* Render anomaly analytic unit config

* Optional HSR #273

* minor fix for #273

* fix codestyle

* minor ui fix

* Improve ui

* render confidence interval

* Update src/panel/graph_panel/controllers/analytic_controller.ts

* use from and to in runDetect
