Add support to edit primary storage IP in UI/API for manual failover/recovery of unaffected instances if primary storage fails

### The required feature described as a wish

[Per this closed issue](https://github.com/apache/cloudstack/discussions/11713) , update API and UI to allow changing the IP address of an existing primary storage pool. This is important for manual failover uses or getting other instances up and running by allowing agents to start with new storage quickly and without modifying the database directly.

该 issue 没有指定文件或测试。首先定位现有的 primary-storage API 和 UI 流程，然后跟踪存储池的 IP 是如何表示和验证的。完成的标准是：无需直接编辑数据库，即可通过 API 和 UI 更改现有 primary storage 池的 IP，并且手动故障转移或恢复可以使用新地址。
