Deleted instances show power state as 'Running'

[Andrew Boik]

After deleting an instance and executing a `nova list --deleted` command as an administrator, the Power State of the deleted instance is still displayed as 'Running' and set to 1 in the database as well.

Steps to reproduce:

    Boot an instance:
    dboik@dboik-VirtualBox:~$ nova boot foo --flavor m1.tiny --image cirros-032-x86_64-uec

    Wait for instance to finish building:
    dboik@dboik-VirtualBox:~$ nova list
    +--------------------------------------+------+--------+------------+-------------+------------------+
    | ID | Name | Status | Task State | Power State | Networks |
    +--------------------------------------+------+--------+------------+-------------+------------------+
    | 2fed0daa-b083-43cf-9285-7364ce4852ce | foo | ACTIVE | - | Running | private=10.0.0.2 |
    +--------------------------------------+------+--------+------------+-------------+------------------+

    Delete the instance:
    dboik@dboik-VirtualBox:~$ nova delete foo
    Request to delete server foo has been accepted.

    As an OpenStack administrator, list the deleted instances:
    dboik@dboik-VirtualBox:~$ nova list --deleted
    +--------------------------------------+------+---------+------------+-------------+------------------+
    | ID | Name | Status | Task State | Power State | Networks |
    +--------------------------------------+------+---------+------------+-------------+------------------+
    | 2fed0daa-b083-43cf-9285-7364ce4852ce | foo | DELETED | - | Running | private=10.0.0.2 |
    +--------------------------------------+------+---------+------------+-------------+------------------+

    Update Power State after deleting instance

    Update the power state for an instance when deleting it.
    Instead of being stuck in the 'Running' power state after deletion,
    a deleted instance will be in the NOSTATE power state.
