Improvement/UI : Show the maximum number of volumes in Hypervisor Capabilities

### The required feature described as a wish

As a Admin/Operator, I would like to see the maximum number of volumes that can be attached to a hypervisor.

In Configuration > Hypervisor capablity

Also, we cannot edit the max volumes supported form the UI

Currently, the api supports it

https://cloudstack.apache.org/api/apidocs-4.22/apis/listHypervisorCapabilities.html
https://cloudstack.apache.org/api/apidocs-4.22/apis/updateHypervisorCapabilities.html

There have been issues with volume attachments in past , setting a max value will help in minimizing them

https://github.com/apache/cloudstack/issues/11212

从 Configuration > Hypervisor capability 开始，检查 issue 中链接的 listHypervisorCapabilities 和 updateHypervisorCapabilities API 条目。跟踪最大卷数值在 UI 中的呈现和更新方式。当支持的最大卷数可见且可编辑，并且更新通过现有 API 得以保留时，即视为完成。

由索引模型根据 Issue 内容生成。
