Summary

Resolves #120678, #120668

Broken out from #124198, this PR adds total_alerts_created and total_alerted_detected metrics (naming discussion) both to the event-log and to the siem-detection-engine-rule-execution-info SO and exposes them as columns on the Rule Monitoring table.

Todo:

  • FTR tests exercising Total Alerts & Total Hits for each rule executor (event-log + logger)

[Security Solution][Detections] Adds rule execution log table (#126215)
9bc4c0c 
## Summary

Resolves #119598, #119599, #101014

Test plan ([internal doc](https://docs.google.com/document/d/1-prIUGYaPHiwGA79CgSdw1926lxIPKGWWkYOUD2BM1U/edit#heading=h.womzsfdt6zt8))

Adds `Rule Execution Log` table to Rule Details page:

</p>


### Implementation notes

The useful metrics within `event-log` for a given rule execution are spread between a few different platform (`execute-start`, `execute`) and security (`execution-metrics`, `status-change`) events. In effort to provide consolidated metrics per rule execution (and avoiding a lot of empty cells and mis-matched statuses like in the image below)

<p align="center">
  <img width="700" src="https://user-images.githubusercontent.com/2946766/151933881-2e58f4d7-4cda-4528-9d44-37cb7bd5de9c.png" />
</p>



these rule execution events are aggregated by their `executionId`, and then fields are merged from each different event. This PR was re-worked to take advantage of the new event-log aggregation support added in #126948, and is no longer implemented as an in-memory aggregation server side.

* Due to restrictions around supplying search filters that may match multiple sub-agg buckets and missing data ([see discussion here](https://github.com/elastic/kibana/pull/127339/files#r825240516)), it was decided that we'd disable the search bar for the time being. We have both a near-term (writing single rollup event) and long-term (ES|QL) solution that will allow us to re-enable this functionality.

* Note, since a `terms` agg is used to fetch all execution events, an upper bound must be set. See [this discussion](https://github.com/elastic/kibana/pull/127339/files#r823035420) for more details, but setting this max to `1000` events for the time being, and returning total cardinality of execution events back within `total` to allow the UI to inform the user that they should narrow their search further to better isolate and find possible issues. This should be a be a reasonable constraint for most all rules as a rule executing every 5 minutes, 1000 executions would cover over 3 days of execution time.

</p>


The `Filter for alerts` action will be available on all `Succeeded`/`Partial Failure` executions even if there weren't alerts generated until #126210 is merged and we can start returning the alert count, at which point we can programmatically enabled/disable this action based on alert count.

Every field in each saved object type adds overhead to Elasticsearch. Kibana needs to keep the total field count below Elasticsearch's default limit of 1000 fields. Only specify field mappings for the fields you wish to search on or query. See https://www.elastic.co/guide/en/kibana/master/development-plugin-saved-objects.html#_mappings

I'm thinking we should probably wait until #135127 is resolved and we migrate our rule statuses and metrics to the Framework (#130966). Then we could add new metrics based on the new mechanism. @spong what do you think?

Yeah @banderror, I was thinking the same thing 🙂. Will be better/easier to just pass this data back as part of the overall status metrics at the end of the execution. I'll comment over on #130966 referencing this as and example for adding alerts detected/created, and then close out this PR.
