Alerting: Time Intervals API (#88201)

* expose ngalert API to public
* add delete action to time-intervals
* introduce time-interval model generated by app-platform-sdk from CUE model the fields of the model are chosen to be compatible with the current model
* implement api server
* add feature flag alertingApiServer
---- Test Infra
* update helper to support creating custom users with enterprise permissions
* add generator for Interval model
