Progress towards https://github.com/shotover/shotover-proxy/issues/1507

checking CI

I hit a problem with cassandra_int_tests::cassandra_redis_cache. SimpleRedisCache will send requests into the same connection from two locations in the transforms logic.

• One location expects responses to be returned immediately. - bad
• The other expects responses to be handled on future transform calls - good

We will need to change the bad case to collaborate with the good case on handling responses back from the connection.

There is no clear performance improvement from this change, so I need to investigate further.
