Hi,

Version 6 of this patch series introduces the following changes:

1) Switch from RPiController::Metadata::Overwrite() back to RPiController::Metadata::Merge().  This simplifies the logic in the IPA.

2) Introduce a new change in patch 3/6.  This replaces our use of std::lock_guard with std::scoped_lock to mitigate deadlock when locking multiple mutexes.

3) SensorTimestamp is no longer a draft control.

David, I have removed your R-b tag from 6/6 because of the scope of change.  When you get a chance, could you re-review please?

Thanks,
Naush
