feat(kubevirt_vm): add state=start/stop/restart to manage VM lifecycle
It adds support for starting, stopping, and restarting VirtualMachines. The operations are performed through the KubeVirt restart subresource API (PUT to `subresources.kubevirt.io/v1`). These calls are extracted into a single shared helper function `_call_subresource()` to handle the common flow, i.e., check mode, API call and wait conditions. Moreover, it adds the optional parameter `grace_period_seconds` for stop and start operations. Additionally, it adds unit tests and integration tests for all operations.
