Vlad Zolotarov f94bbc5b34 transport: add per-scheduling-group CQL opcode-specific metrics
This patch extends a previous patch that added these metrics globally:
 - cql_requests_count
 - cql_request_bytes
 - cql_response_bytes

This patch adds a "scheduling_group_name" label to these metrics and changes corresponding
counters to be accounted on a per-scheduling-group level.

As a bonus this patch also marks all 3 metrics as 'skip_when_empty'.

Ref #13061
