[Stack Monitoring] [Test Scenario] Metricbeat monitoring

[estermv]

Testing

• Ensure that the Stack Monitoring UI works as expected with both metricbeat-* data and .monitoring-* data ([Monitoring] Handle no mappings found for sort and collapse fields #77099). This involves using either legacy or Metricbeat-based collection in addition to using Metricbeat for non-stack monitoring data. The easiest way to do this is to setup monitoring via Metricbeat and ensure the system module is enabled.

This test scenario was for a specific fix done for 7.10. If at some point the bug appears again, we can add the specific configuration and run the existing tests with this configuration.
