以无配置方式AKSK调用云服务API

KooCLI支持在命令中添加“--cli-access-key”，“--cli-secret-key”和“--cli-security-token”选项，以无配置方式AKSK调用云服务API。

当命令中仅使用“--cli-access-key”和“--cli-secret-key”时，默认识别该AK，SK为永久AK/SK：

hcloud RDS ListApiVersion --cli-region="cn-north-4" --cli-access-key=******** --cli-secret-key=********
{
  "versions": [
    {
      "id": "v3",
      "links": [],
      "status": "CURRENT",
      "updated": "2019-01-15T12:00:00Z"
    },
    {
      "id": "v1",
      "links": [],
      "status": "DEPRECATED",
      "updated": "2017-02-07T17:34:02Z"
    }
  ]
}

当命令中同时使用“--cli-access-key”，“--cli-secret-key”和“--cli-security-token”时，默认识别该AK，SK为临时AK/SK：

hcloud RDS ListApiVersion --cli-region="cn-north-4" --cli-access-key=******** --cli-secret-key=******** --cli-security-token=********
{
  "versions": [
    {
      "id": "v3",
      "links": [],
      "status": "CURRENT",
      "updated": "2019-01-15T12:00:00Z"
    },
    {
      "id": "v1",
      "links": [],
      "status": "DEPRECATED",
      "updated": "2017-02-07T17:34:02Z"
    }
  ]
}
