…egy in redis-py 6+ redis-py 6 refactored ClusterPipeline so that queued commands are no longer appended to `command_stack`; they now live on `_execution_strategy.command_queue`. As a result the redis instrumentor emitted ClusterPipeline spans with an empty DB_STATEMENT and a `db.redis.pipeline_length` of 0. `_build_span_meta_data_for_pipeline` now reads commands from `_execution_strategy.command_queue` when present, falling back to `command_stack` / `_command_stack` for non-cluster pipelines and older redis-py versions. Fixes open-telemetry#4084

Description
redis-py 6 refactored
ClusterPipelineso that queued commands are no longer appended tocommand_stack(which still exists but stays empty); they are now tracked on_execution_strategy.command_queue. Because_build_span_meta_data_for_pipelineread commands fromcommand_stack,ClusterPipelinespans under redis-py 6+ were emitted with an emptydb.statementand adb.redis.pipeline_lengthof 0.This change makes
_build_span_meta_data_for_pipelineread commands from_execution_strategy.command_queuewhen present, falling back tocommand_stack/_command_stackfor non-cluster pipelines and older redis-py versions.This revives the approach from #4436 (closed by the stale bot for inactivity after a maintainer reviewed it positively) and adds the changelog fragment via towncrier.
Fixes #4084
