Fuel CLI doesn't really deletes nodes

[Ivan Ponomarev]

Step to reproduce:
1) Deploy 3 controller 1 compute
2) Shutdown one node offline and wait when it goes offline
3) Delete this node from CLI
[root@nailgun ~]# fuel --env 1 node remove --node 1
Nodes with ids [1] were removed from environment with id 1.
4) List nodes on CLI/UI

Expected result:
Node should be deleted.
node_deletion task should exists

Actual result:
Node still in list.
node_deletion task not in task list
Retrying for deletion return:
[root@nailgun ~]# fuel node remove --node 1
400 Client Error: Bad Request (Can't unassign nodes with ids <nailgun.db.sqlalchemy.models.node.Node object at 0x61d1810> if they not assigned.)

This bug is invalid because you should have used

`fuel node --node-id 1 --delete-from-db` and taken care of this node by yourselves

@vkuklin
You want say that node can't be deleted from CLI like from UI?
I mean when you delete offline node from UI the other nodes starts redeploy process, how can I do this by CLI
Or it should be described in cocs
