the OS::stack_id of k8sbay is ip rather than id

[PanFengyun]

1.when I use "openstack stack output list <stack_id>", can't get the description of output_key.

$ openstack stack output list k8sbay-moj5vd2vnx52-kube_minions-tkv2pnkpvdle-0-lzi62huvhql5
+-------------------------+----------------------+
| output_key | description |
+-------------------------+----------------------+
| kube_minion_external_ip | No description given |
| kube_minion_ip | No description given |
| OS::stack_id | No description given |
+-------------------------+----------------------+

2.when I use "openstack stack output <stack_id> OS::stack_id", can't get a stack id and it output the private ip of node.
$ openstack stack output show k8sbay-moj5vd2vnx52-kube_minions-tkv2pnkpvdle-0-lzi62huvhql5 kube_minion_ip
+--------------+----------------------+
| Field | Value |
+--------------+----------------------+
| description | No description given |
| output_key | kube_minion_ip |
| output_value | 10.0.0.5 |
+--------------+----------------------+
$ openstack stack output show k8sbay-moj5vd2vnx52-kube_minions-tkv2pnkpvdle-0-lzi62huvhql5 OS::stack_id
+--------------+----------------------+
| Field | Value |
+--------------+----------------------+
| description | No description given |
| output_key | OS::stack_id |
| output_value | 10.0.0.5 |
+--------------+----------------------+

$ openstack stack show k8sbay-moj5vd2vnx52-kube_minions-tkv2pnkpvdle-0-lzi62huvhql5 | grep OS::stack_id
| | OS::stack_id: 4dd06a7e-c9d7-4128-8176-25bd04d5b3d8 |
| | output_key: OS::stack_id

    Fix OS::stack_id is set as stack id instead of private ip

    The OS::stack_id of k8sbay'd stack should be set stack id rather
    than kube_minion_ip.
    'value: {get_attr: [kube_minion_eth0, fixed_ips, 0, ip_address]}'
    -->
    'value: {get_param: "OS::stack_id"}'
