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

[kiranchavala]

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
