## Summary
This PR adds changes and instructions how to run existing performance
journeys against ESS instances.
As previously discussed with @pheyos , there are few manual steps to be
done before running the actual journey:
1. Create cloud deployment and re-configure it the way APM traces are
reported the monitoring cluster
2. Check out the branch matching deployment version (main ->
8.9.0-SNAPSHOT), create user with `superuser` role (we don't test
functional features, only performance metrics)
Then you can run the journey like a regular cloud test suite:
```
export TEST_KIBANA_URL=https://<username>:<password>@<kibana_url>
export TEST_ES_URL=https://<username>:<password>@j<elasticsearch_url>:<port>
export TEST_CLOUD=1
node scripts/functional_test_runner.js --config x-pack/performance/journeys/$YOUR_JOURNEY_NAME.ts
```

This PR updates docs around Kibana performance effort:
- how to create single user performance journeys, custom metrics with
EBT and review test results
- how to create api capacity test and where to find its test results
