[Tracking]: Beam 3.0.0 Milestone 1 Python SDK breaking changes #36101
Description
What needs to happen?
This umbrella issue tracks any changes could affect existing users (breaking changes) made to Beam Python SDK as part of Beam 3 effort. Changes not necessarily happen for 2.x -> 3.0 at once. Instead incrementally, and actual breaking change happens at Beam 3.0.0 (Milestone 3).
