In-memory database for stream health analyzer

[victorges]

We're having to write a lot of boilerplate both to store, read and process data in the healthcore system. We should probably leverage from some existing local DB that could facilitate a bunch of those stuff for us. Bonus if it is distributed and analyzer instances could communicate through it somehow.
