[Infrastructure UI] Filter control re-rendering problem fix (elastic#…

…159320)

fixes elastic#159317 

## Summary

This PR fixes a problem in the utilization of the `ControlGroupRenderer`
component in the Hosts View. The problem originated from the need to
manually compare changes in the `filterPanel` object, to prevent the
page from making duplicate requests


https://github.com/elastic/kibana/assets/2767137/b38f5691-0519-4ae2-aab2-daaf0f72cd0d

After many changes that the code has been through, the comparison
mentioned above has become unnecessary.



### How to test

- Start a local Kibana instance
- Navigate to `Infrastructure > Hosts`
- Play with the filter controls (depending on how fast the user is, it
might hang for a little while, but this won't slow the whole page down)
