Went over it quickly and it looks good. One question though, how would this work if we want to backfill some accounts or run account flushes to reindex some accounts? |
…ingester using dedicate exec
…est stream which handle reading messages and handling messages.

Goal
Reduce the operational cost and complexity of running DAS by switching to Dragonmouth grpc stream for account and transaction updates.
Upgrade the ingestion engine by refactoring configuration, workers, and metrics.
Approach
Create a new crate named das-grpc-ingest which has 3 primary subcommands.
stream - connects to Dragonmouth and pushes relevant events into a redis queue
ingest - subscribes to redis streams, spawns workers, and processes events using program_transformers crate.
download - fetches metadata json for asset_data replacement to bgtasks
Based on #144
closes #83
