feat(sds): add retrieval hint to causal history

[adklempner]

Problem / Description

The protobuf definition for SDS messages was recently update to include a retrieval hint with every message stored in the causal history.

Solution

Update protobuf definition.
Update functions which touch causal history to work with the new structure.
Update the callbacks passed when sending messages to return the retrieval hint.

Notes

• Resolves sds: Update causal history and local log to include retrieval hint #2301
• Depends on feat(sds): adds ephemeral messages, delivered message callback and event #2302
