fuel cli removes all nodes when misspelt

[Andrey Danin]

When you forgot set appropriate node-id's, the Fuel CLI drops roles and cluster_id for all nodes in DB.

[root@fuel ~]# fuel --env 2 node 14 --delete

Nodes with ids [1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 27, 28, 29, 30, 31, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43] were removed from environment with id 2.
