Closing this PR as we decided to just reset NiFi Registry in order to
switch Persistence Providers until more reliable export/import commands are
added. See [NIFIREG-162](https://issues.apache.org/jira/browse/NIFIREG-162) for
detail.

>
> In NiFi Registry project, there is an improvement to add new
> FlowPersistenceProvider which can utilize Git technology.
> We need to provide a tool to migrate existing Flow snapshots those are
> persisted with the FileSystemFlowPersistenceProvider, so that users can
> switch from that to new Git persistence provider, or vise versa.
> A possible approach is taking a providers.xml file and a URL of running NiFi
> Registry with a FlowPersistenceProvider which is currently used, then extract
> all Flow snapshots then persist those with the new PersistenceProvider. This
> way, existing Flow snapshots can be extracted into the new
> PersistenceProvider storage. After that, NiFi Registry can be configured to
> use new provider with existing Flow snapshots.
