Description

Since the release of git persistence for flow storage, many users have asked if there is a way to stand up a new NiFi Registry instance and just point it at an existing git repo of flows.

Currently the issue is that the git repo is only used for the persistence of flow content, and the metadata comes from a relational database, so if you lost your server and don't have a copy of the DB then the git repo alone isn't enough.

In general the DB should be backed up, or an external DB with HA (Postgres) should be used instead of the H2 DB, but we should also be able to offer a way to bootstrap a new NiFi Registry instance from a git repo of flows.
