Title Pluggable mechanism for storing / retrieving StateDB and Ledger Files (e.g., for Better Analysis)using MongoDB Status Status colour BlueRed title Pending TSC Reviewcancelled Difficulty   Status colour Yellow title Medium

Description 

Presently, Fabric stores StateDB in CouchDB or goLevelDB. Create a pluggable mechanism for storing StateDB in using MongoDB.

Also, create a pluggable mechanism for storing ledger files in a database such as MongoMongoDB. This mechanism will not only help make data stores truly pluggable, but also make easy to analyze Hyperledger Fabric data natively using MongoDB. Analzying Fabric data (e.g., for provenance) is currently a huge challenge and requires creation/setup of a separate infrastructure.
