StreamingManager does not load data already cached by cacache

[tsxiaofang]

The existing cache becomes invalid every time the service restarts.

I've been making a lot of changes and fixes to streaming lately so I will recreate this issue and gauge the state of things. Thanks for the report!

This ended up being a journey, after resolving other issues were uncovered. I ended up redoing the streaming cache implementation. I think it's good to go but still testing. The streaming logic is still very new

This should now be resolved in alpha.7 but I made a lot of changes to the streaming backend so expect a rebuild of the cache.
