Add filtering on metric name to label_values

[roman-vynar]

Currently, Prometheus supports the following HTTP API call to retrieve all label values by its name:
/label/:name/values

It would be great to extend this with some kind of filtering on metric name, so you can get label values limited to the given metric.

For example, the label is device and I would like to get device name values only for the metric node_filesystem_free and not node_network_receive_bytes or other.

Say something like /label/:name/values?metric=:metric

Thanks!

Closing this, I realized that something more complex needed 😇
