As per the request from the TC, here is a work in progress review for the redis impl. its a POC. Plz understand that its more about seeing how this affects the trove codebase than scrutinizing why i did X or Y in the redis impl, or whether i should include config value Z. <3

Ive done a proof of concept for redis and it was ~200 lines of guest impl code and I had to make one small change to the core create API, but one that will be the new default for creating instances. It was adding a return of a root password. the other differences were the /users and /databases extensions for mysql were not working (for obvious reasons). The reason NRDB was not originally part of Trove was a decision that there was nothing to show that it has a valid impl without substantial differences to the API/core system [1].

>> The path for it is to basically add a redis.py to the guest impl and to instruct the api that redis is the default (config file). Then the api/functionality behaves the same. Feel free to ask questions on list before the tc meeting!
