feat: add otel_scope_info and scope labels

[zengxilong]

PR for #930

1. Add otel_scope_name and otel_scope_version attributes to all metrics based on the instrumentation scope name and version.
2. Add an otel_scope_info metric.
3. Add prometheus exporter config, provide a disable_scope_info flag to disable the otel_scope_info metric and otel_scope_ labels.
4. I will make a new PR to resolve collisions between TYPE, HELP, and UNIT comments.

Thanks for working on this. Overall like a good start. I think maybe use something like with_scope_info will be more clear. And we can have the default value to be true
