[WIP] Diagnostic telemetry sender

[tsg]

Summary

This is for the implementation of the Kibana task that reads the data from the diagnostics index and ships it to our telemetry service.

The rough plan is to:

• create a task manager task that is executed every ~5 minutes

• on each execution:

  • check if telemetry is enabled. If it's disabled, do nothing
  • query the index we decide to for the time since last execution to present, sorting by the event.ingested field. Limit the result set to 100 events.

• call the queueTelemetryEvents function from the EventsTelemetry component added in [Security] Alert Telemetry for the Security app #77200

• record the last execution time
