Add service management API to Karbor¶

https://blueprints.launchpad.net/karbor/+spec/karbor-service-management

Problem description¶

Currently, karbor does not have service management API for karbor services (karbor-operationengine and karbor-protection). We can find that service management API has been in almost all the other OpenStack projects. It is very convenient for admin to list/enable/disable the services on any nodes.

Use Cases¶

Admin want to list/enable/disable karbor services on any karbor nodes.

Proposed change¶

Add service management API controller for the Karbor API.

Implement the ‘index’ method of service management API controller. Implement the ‘update’ method of service management API controller.

Add service management to karbor client.

Alternatives¶

None

Data model impact¶

None

REST API impact¶

1. List services API The response JSON when listing services:

**get** : /v1/{project_id}/os-services
```json
{
  "services": [
    {
      "status": "enabled",
      "binary": "karbor-operationengine",
      "disabled_reason": null,
      "host": "karbor@node",
      "updated_at": "2017-09-07T13:03:57.000000",
      "state": "up",
      "id": 1
    },
    {
      "status": "enabled",
      "binary": "karbor-protection",
      "disabled_reason": null,
      "host": "karbor@node",
      "updated_at": "2017-09-07T13:03:57.000000",
      "state": "up",
      "id": 2
    }
  ]
}

2. Update service API The request JSON when updating service:

**put** : /v1/{project_id}/os-services/{service_id}
```json
{
  "status": "enable"
}

The response JSON when updating service:

```json
{
  "service": {
    "id": "e81d66a4-ddd3-4aba-8a84-171d1cb4d339",
    "binary": "karbor-protection",
    "disabled_reason": null,
    "host": "karbor@node",
    "state": "up",
    "status": "enabled",
    "updated_at": "2012-10-29T13:42:05.000000",
  }
}
