deleting overcloud but stack is not DELETE_IN_PROGRESS

[PanFengyun]

After excuting "heat stack-delete overcloud", the stack_status of overcloud is not DELETE_IN_PROGRESS.

Reduction step:
1.deploying overcloud
---------
# openstack overcloud deploy --templates ~/templates/my-overcloud --control-scale 1 --compute-scale 1 --control-flavor control --compute-flavor compute --neutron-public-interface nic1 --neutron-network-type vxlan --neutron-tunnel-types vxlan --ntp-server 192.168.220.5
# heat stack-list
+--------------------------------------+------------+--------------------+---------------------+--------------+
| id | stack_name | stack_status | creation_time | updated_time |
+--------------------------------------+------------+--------------------+---------------------+--------------+
| 47b54ecb-b010-475d-81fd-619fcc9b601f | overcloud | CREATE_COMPLETE | 2016-03-11T14:52:02 | None |
+--------------------------------------+------------+--------------------+---------------------+--------------+
---------
2.delete overcloud
----------
# heat stack-delete overcloud
+--------------------------------------+------------+-----------------+---------------------+--------------+
| id | stack_name | stack_status | creation_time | updated_time |
+--------------------------------------+------------+-----------------+---------------------+--------------+
| 47b54ecb-b010-475d-81fd-619fcc9b601f | overcloud | CREATE_COMPLETE | 2016-03-11T14:52:02 | None |
+--------------------------------------+------------+-----------------+---------------------+--------------+
# heat stack-list
+--------------------------------------+------------+--------------------+---------------------+--------------+
| id | stack_name | stack_status | creation_time | updated_time |
+--------------------------------------+------------+--------------------+---------------------+--------------+
| 47b54ecb-b010-475d-81fd-619fcc9b601f | overcloud | DELETE_IN_PROGRESS | 2016-03-11T14:52:02 | None |
+--------------------------------------+------------+--------------------+---------------------+--------------+
----------

Desired result:
# heat stack-delete overcloud
+--------------------------------------+------------+--------------------+---------------------+--------------+
| id | stack_name | stack_status | creation_time | updated_time |
+--------------------------------------+------------+--------------------+---------------------+--------------+
| 47b54ecb-b010-475d-81fd-619fcc9b601f | overcloud | DELETE_IN_PROGRESS | 2016-03-11T14:52:02 | None |
+--------------------------------------+------------+--------------------+---------------------+--------------+

reason:
investigating

I don't really think there is a bug, or at least I know why it's doing this: the delete operation is asynchronous, and doesn't return anything. To account for that, the client just does a stack-show after the delete, to return something to display. But at that point, the delete may not be already in progress.

Arguably we could remove that show, but can't because of compatibility.

[PanFengyun (pan-feng-yun)]

its reason:
stack-delete command will do :
1.do_stack_delete()
2.do_stack_list()

I think stack-delete command shoud not do do_stack_list.

    stack-delete command should not call do_stack_list.

    the stack-delete operation is asynchronous, and should not return
    anything.
