ref(replays): Remove dead code and reorganize ingest-replay-recordings consumer

[cmanallen]

Problem statement:

There was a variety of code paths which were no longer used. These were dropped. Additionally some of the code was not well factored. Too many concerns were put into one module and which reduced its ability to integrate with multiple systems and also led to weird control flow for cross module communication. This has been refactored and unit test and integration test coverage has been added.
