Luna Stadler f4114f02d4 Fetch only the required podMetrics for the given component (#17489 )

The `PodMetrics` are now limited by `labelSelector` like already done
for pods and probably other requests to Kubernetes.  This limits the
amount of data that is fetched.

Tested locally by modifying `app-config.yaml` and an example component
to use an internal cluster, which leads to the following request size
improvements:

Before: 344.71 kB compressed, 6.89 MB uncompressed
After: 12.01 kB compressed, 238.86 kB uncompressed

For the POST http://localhost:7007/api/kubernetes/services/playback-order
call, in a Kubernetes cluster with ~500 pods.

Fixes #17450.

Allow fetching pod metrics limited by a labelSelector.

This is used by the Kubernetes tab on a components' page and leads to much smaller responses being received from Kubernetes, especially with larger Kubernetes clusters.
