[Stack Monitoring] implement baseline elasticsearch api tests for pac…

…kage and metricbeat data (#149161)

### Summary

Part of #148303
Closes #146067
Closes #146068

I investigated the failing tests but couldn't get to the root cause
quickly enough so I took the opportunity to port the tests to the
[monitoring_api_integration](https://github.com/elastic/kibana/tree/main/x-pack/test/monitoring_api_integration)
suite. This reimplements all the existing tests (plus missing ones for
the `ml_jobs` api) with fresh data.
By using the new testing approach we can remove the archived mappings
which greatly reduce execution times.

### Testing
- The suite was executed against by the [flaky test
runner](https://buildkite.com/elastic/kibana-flaky-test-suite-runner/builds/1804)
multiple times with no failures
- Test data is bundled in two archives (one for metricbeat and one for
package data) and can be loaded to verify their content: `node
scripts/es_archiver.js load
x-pack/test/monitoring_api_integration/archives/elasticsearch/single_node/(package|metricbeat)
--es-url=http://elastic:changeme@localhost:9200
--kibana-url=http://elastic:changeme@localhost:5601`
