#3307 feat: Allow the user to override stream and sink meters (i.e. counters & timers) Pull request opened by edgarrmondragon ## Summary by Sourcery Introduce overrideable metrics getters for stream and sink counters and timers and refactor usage to centralize context handling via a new with_context method. New Features: • Add get_record_counter, get_batch_counter, and get_sync_timer methods to Stream core for customizable counters and timers • Add get_sink_record_counter and get_batch_processing_timer methods to Sink core for customizable sink metrics • Add get_http_request_counter method to RESTStream for customizable HTTP request metrics Enhancements: • Refactor stream and sink implementations to use the new get_* methods instead of direct metrics calls • Unify meter context handling by replacing direct context assignments with the new with_context method in metrics • Deprecate the metrics.Counter.context setter in favor of with_context meltano/sdk
