Cap Block Streamer Caching and Merge Redis Impl

[darunrs]

Redis memory usage is pegged at 100% due to Block Streamer backfilling * contract filter indexers.

In addition, Redis implementation of Coordinator and Block Streamer have diverged. Coordinator is also not able to make successful calls to Redis. While not a targeted fix, the hope is that merging the implementation fixes the issue as Block Streamer is able to make calls to Redis.

Before release, some manual intervention is necessary in dev and prod to update versions of indexers to the current, to prevent unwanted behavior from coordinator. I will do dev first, release the change, and then do prod before a prod release.
