Update kubernetes controller manager metrics and dashboard

[MichaelKatsoulis]

Continuing the work done in #31973 Kubernetes controllermanager metricset should be updated.

Some of the metrics collected by Kubernetes controllermanager metricset are deprecated in newer versions of Kubernetes.

Currently we support k8s versions starting from 1.21.x so there is no need to keep searching for older versions' fields in current/newer versions of beats.

The following controller manager prometheus metrics are deprecated. Probably some of them have been substituted by other fields we are not currently collecting. This needs to be investigated.

http_request_duration_microseconds
http_request_size_bytes          
http_response_size_bytes                
http_requests_total                    

Also the OOTB dashboard should be updated as currently some visualisations are broken.
