If redis is available, then we can use it, I think we can do it by conditionally passing the redis in the constructor, and handle optionality on creation level

dependent #716
Issue
We need to implement endpoints with SSE which allows to get in real time updates of indexer
Things done
keep-aliveconnectionImplemented events based blocks pool, which allows blocks to be sent in the correct order, otherwise the sending order will be disrupted due to different waiting times for several blocks with consecutive transactions or any other delaysImplementedgetBlockWithTransactionforBlocksDAORedisConnection, which allows to interact with redis via only 2 connections
