* remove pipeline serialization from telemetry * simplify getting component instance from pipeline * reno * add unit test with non-serializable component * generate qualified class names * added pipeline.walk() * fix imports * sort Iterator import * remove bfs * add test for pipeline.walk() with cycles * Apply suggestions from code review Co-authored-by: Madeesh Kannan <shadeMe@users.noreply.github.com> * raise TypeError if telemetry_data is no dict * Update haystack/telemetry/_telemetry.py Co-authored-by: Madeesh Kannan <shadeMe@users.noreply.github.com> --------- Co-authored-by: Madeesh Kannan <shadeMe@users.noreply.github.com>
