…#55201)

* adds logic for returning / updating status when a rule is switched from enabled to disabled and vice versa.

* update response for find rules statuses to include current status and failures

* update status on demand and on enable/disable

* adds ternary to allow removal of 'let'

* adds savedObjectsClient to the add and upate prepackaged rules and import rules route.

* fix bug where convertToSnakeCase would throw error 'cannot convert null or undefined to object' if passed null

* genericize snake_case converter and updates isAuthorized to snake_case (different situation)

* renaming to 'going to run' instead of executing because when task manager exits because of api key error it won't write the error status so the actual status is 'going to run' on the next interval. This is more accurate than being stuck on 'executing' because of an error we don't control and can't write a status for.

* fix missed merge conflict
