Description

We currently have the options of local filesystem and git for flow storage. While git is for pushing to a remote and visualizing in github, it is only a one way push and not ideal for an HA scenario where we would want multiple instances of the NiFi Registry application running.

We should implement a FlowStorageProvider backed by a relational database table that could live in the same DB as the metadata database. This would allow multiple NiFi Registry instances to run pointing at the same external database.
