Investigate dependence on (and prepare for changes to) DeliverTX Events and Log

[adizere]

Summary

SDK is planning a refactor of DeliverTX responses: cosmos/cosmos-sdk#15017.
I suspect Hermes depends on this surface, see below for example:

hermes/crates/relayer/src/event/rpc.rs

Line 117 in 097c5df

pub fn get_all_events(

Suggested actions: allocate time to

• engage with the SDK team to inform their new design/refactoring, because any change has the potential to simplify (or break) the relayer
• prepare for breaking changes
• inform the design for relayer-next based on the refactoring that the SDK is doing
