Stabilize and normalize 13/WAKU2-STORE RFC

[LNSD]

Problem

From #528:

The protocols specified in the following RFCs are ready for the stable status:

• 10/WAKU2
• 13/WAKU2-STORE
• 14/WAKU2-MESSAGE
• 15/WAKU-BRIDGE

Acceptance criteria

• Make the RFC conform to the RFC template
• Add the new protocol's wire format (v3) to the waku store RFC. Deprecate v2-beta4
• Merged 21/WAKU2-FAULT-TOLERANT-STORE's wire specification into 13/WAKU2-STORE
• Add current Waku Store protobuf definitions to the waku protobuf repository (v2-alpha4)
• Add the new Waku Store protobuf version(v3)

Notes

This task has a dependency on #551

Merged 21/WAKU2-FAULT-TOLERANT-STORE's wire specification into 13/WAKU2-STORE

Regarding the above item, I would suggest to get an agreement before attempting it. The separation of these two RFCs was intentional. Since the time query feature was emerged from the need to make store protocol fault-tolerant against nodes with poor connectivity, the decision was to capture the problem together with the solution in a separate specification. Potentially, this specification i.e., FT-Store can evolve and include more solutions for handling faulty nodes.

Update: Is my interpretation of this task correct? do you want to merge them? or just include the start_time and end_time fields in the HistoryQuery protobuf definition?

Indeed! The two RFCs must remain separate. This task is simply to include the start_time and end_time fields in the general Store protobuf definitions. :)
This is so we can stabilise STORE which is being used widely with the time fields (e.g. by Status) without having to also stabilise FT-STORE (which will remain separate and in draft).

Is my interpretation of this task correct? do you want to merge them? or just include the start_time and end_time fields in the HistoryQuery protobuf definition?

The latter 😄 . FT-STORE must remain its own spec.

The Waku store v3 wire format has been sketched in the following draft PR: waku-org/waku-proto#10

Closing as it seems discussion is complete.
