Append metric labels as dimensions

[andreas-ahman]

Today the metrics contain labels that are not added as Dimensions when sent in.

for example these metrics consul.api.http

    {
      "Name": "consul.api.http",
      "Count": 1,
      "Rate": 0.034217000007629395,
      "Sum": 0.34217000007629395,
      "Min": 0.34217000007629395,
      "Max": 0.34217000007629395,
      "Mean": 0.34217000007629395,
      "Stddev": 0,
      "Labels": {
        "method": "PUT",
        "path": "v1_agent_check_update_"
      }
    }

The label method and path are not added as dimensions.

This change would allow for these labels to be added as dimensions.

Hi @andreas-ahman thanks for opening - seems like a reasonable change to me.
Can you add some labels to the existing tests to verify the functionality?

I've added the metrics in the tests. I hope it's what you're looking for.
