[OpenStack] floating_ip is actually floating_ip_id

从 issue 中链接的 OpenStack builder 文档部分以及使用 floating_ip 的简化 buildfile 开始。使用一个地址和一个 ID 重现不匹配，然后根据报告的错误追踪 builder 对 floating-IP 的查找过程。文档中的输入与 builder 接受的值一致，并且已覆盖报告的案例，即表示完成。

This issue was originally opened by @gkoudjou as hashicorp/packer#8300. It was migrated here as a result of the Packer plugin split. The original body of the issue is below.

Overview of the Issue

According to the documentation, with the Openstack builders, we can defined a specific floating IP address.

https://www.packer.io/docs/builders/openstack.html#floating_ip

While testing, it appears that packer expects an ID.

Reproduction Steps

Here is some json file :

    "builders": [
        {
            "type": "openstack",
            "username": "{{user `username`}}",
            "password": "{{user `password`}}",
            "identity_endpoint": "XXXXXXXXX",
            "region": "regionOne",
            "image_name": "{{user `image_name`}}",
            "instance_name": "packer-test",
            "ssh_timeout": "5m",
            "floating_ip_network": "external",
            "floating_ip": "10.121.240.228",
            ]
        }
    ],

And here is the result :

openstack output will be in this color.

==> openstack: Loading flavor: Tiny_Linux
    openstack: Verified flavor. ID: 1
==> openstack: Not using temporary keypair
    openstack: Found Image ID: d91327b6-ef25-4632-b866-8773927c6a83

==> Some builds didn't complete successfully and had errors:

But if a use the ID used by requesting openstack, it's working.

openstack output will be in this color.
