Hello Team, We are planning to upgrade our use of NiFi from 1.x to 2.x, and we are looking very much forward to try the new version. In NiFi 1.x we are using the "file-manager.sh" script in the toolkit for making backup and restore. It appears that this file is no longer present in NiFi 2.x. 1) Has this file been removed from NiFi 2.x permanently, or do you know of any plans for adding it to NiFi 2.x in a future release?  2) If the file is not coming to NiFi 2.x will there be any replacement file for making backup/restore, or should we collect files for backup ourselves such as flow.json.gz?
