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

In my current project, I need the instrumentation scope name as a dimension in the exported span metrics.

Describe the solution you'd like

Ideally, a new option instrumentation_scope that allows you to configure which part of the scope should be included as a dimension:

spanmetrics:
  instrumentation_scope:
    name: true
    version: false

Additionally, dimensions should also look at the instrumentation scope attributes.

Describe alternatives you've considered

Alternative, I'd have to add the name of the instrumentation scope to the span's attributes before it's send to the collector and then use the dimensions option. This isn't ideal, since every span would now have an additional tag.
