extension: improve host vm power reporting

[shwstppr]

Description

Add statuses action in extensions to report VM power states

This PR introduces support for retrieving the power state of all VMs on a host directly from an extension using the new statuses action.
When available, this provides a single aggregated response, reducing the need for multiple calls.

If the extension does not implement statuses, the server will gracefully fall back to querying individual VMs using the existing status action.

Pull Request Overview

This PR introduces a new statuses action to extensions that allows querying the power state of all VMs on a host with a single call, improving efficiency over individual VM queries. The server gracefully falls back to the existing status action when the extension doesn't support the new functionality.

Key changes:

• Add statuses action implementation to existing extensions (Proxmox, HyperV, sample provisioner)
• Implement Java logic to use batch VM status retrieval with fallback to individual calls
• Add comprehensive test coverage for the new functionality

The deprecated new JsonParser().parse() method has been replaced with JsonParser.parseString(), but this change should be consistent throughout the file. The same pattern should be applied to line 702 where JsonParser.parseString() is used in the new code.
