[don't merge] time skipping sleep: need review and server PR

[feiyang3cat]

What changed?

1. Removed obsolete fields — safe to delete as this feature has not been released (disable compatibility checking temporarily)
2. Renamed bound to sleep timer to match the previous semantics exposed by the SDK Testing server
3. Add disable_propagation_for_child to give users a way to stop propagation

Why?

1. for 1) make the API cleaner
2. for 2) simplify user experience

• sleep is a simpler and cleaner concept than bound for user experience and backward compatibility

3. for 3) a child workflow is a different execution and has its own virtual clock, and users may need an option to change the default propagation behavior

Breaking changes

1. removed the feature maxSkippedDuration-> the server has already implemented this feature need to delete the code first
2. restructured the maxElapsedDurationto sleep-> the server need to do renaming
