In order to improve the reconnection delay when a client queries realtime API using parts and offsets, we need to update the KSQLDB configuration and ecs instance cpu/memory configurations in our prod env.

To do

• Update Ksqldb configurations that was tested in dev
• Update ECS instance cpu/memory that was tested in dev

QA/Acceptance criteria

• Test the prod API, use experiments/realtime-stress-test repo test-by-offsets test. We should see the worst delay around 270 seconds.
