/kind enhancement
/cc @stackitcloud/ske-infrastructure

What this PR does / why we need it:
This PR will change the metrics from cloud_provider_stackit_http.* to stackit_api_http.*.
The metrics do not contain an API label anymore which needed to be configured. They now contain the host of the API which contains the same information. Also the op labe was renamed to operation label and now contains the function name from the SDK. It also contains a component which can be different within the same repo, like cloud-controller-manager and stackit-csi-plugin.

The metrics package can be used the same way also in other repos later like application-load-balancer-controller.

Special notes for your reviewer:

Breaking changes:
/label breaking
