Add ability to exclude nodes by labels

[sergeyshevch]

What would you like to be added:
#694
We use part of our nodes as AWS EKS Fargate. The metrics server cannot fetch metrics from these nodes. But it still trying to scrape it.
As a result metrics_server_kubelet_request_total{success="false"} reports a high error rate and it's become harder to create correct alerts based on it.

Why is this needed:
It will allow to exclude some nodes and fix issues with failed scrapes in metrics/logs
