[Alerting][Telemetry] Investigate what transformations are applied to alerting telemetry

[ymao1]

Based on these comment

One thing to note is the telemetry team is able to perform transformations on the data in the "middle layer" of the process (which is basically a cloud service that sits in the middle of Kibana sending the data, and it being indexed into the ES cluster) so it's possible to fix any issues outside of our deployment model

The transformations are part of the new telemetry system we've been building out

We should investigate:

• What, if any, transformations are currently being applied to alerting telemetry data
• What, if any, transformations should we think about applying to alerting telemetry data. I would specifically start with the usage counter information that we're tracking but this could also apply to any alerting telemetry.

Closing as we've moved our telemetry to the response ops indexer.
