Summary

as stated in https://github.com/elastic/kibana-team/issues/2885#issuecomment-3926987437, control plane is in control of the cpsEnabled flag, and thus we need to remove our explicit configuration of that flag to remove interference with control plane's settings.

I'm curious how that would work for our local development and CI for the specific tiers. What would the sync behavior be from the controller to our local dev and CI setup? For instance, if I run Kibana in a Security Essentials tier where CPS is disabled, how can I validate that nothing is broken and working as intended (e.g, some code doesn't account for unavailable CPS)? Are developers expected to know the CPS status for specific tiers and set this manually, or is there a more robust way to handle this?
