processor/spanmetrics

Is your feature request related to a problem? Please describe.

Currently, if there is no error (ie. no error=true tag in spans) we don't create any metric with prometheus label as status_code = "STATUS_CODE_ERROR". This generates empty dashboard.

Describe the solution you'd like

We would like to instead have prometheus metric with label as status_code = "STATUS_CODE_ERROR" and value as 0.

Describe alternatives you've considered
