* Use redb and in Dockerfiles The motivation for redb was to remove the multiple rocksdb compile times from CI. * Correct feature flagging of coordinator and message-queue in Dockerfiles * Correct message-queue DB type alias * Use consistent table typing in redb * Correct rebase artifacts * Correct removal of binaries feature from message-queue * Correct processor feature flagging * Replace redb with parity-db It still has much better compile times yet doesn't block when creating multiple transactions. It also is actively maintained and doesn't grow our tree. The MPT aspects are irrelevant. * Correct stray Redb * clippy warning * Correct txn get
