Unable to destroy/expunge systemvm in a multihypervisor cluster/environment

### problem

Unable to destroy/expunge systemvm in a multihypervisor cluster/environment

### versions

ACS 4.22

### The steps to reproduce the bug

1. Create a Cloudstack environment with 2 clusters ( vmware , KVM)

2. Launch systemvm's on the vmware cluster, make sure they are in running state

3. Shutdown the vmware vcenter cluster , the system vm's will be running state , but the agent will be in a disconnected state

4. Mark the zone is disabled and try to stop or destroy the systemvm's

5. Exception observed

```

Tried reducing the value of the expunge.delay and expunge.interval

Workaround

Manually update the database and set the removed date

mysql>update vm_instance set removed=now() where id=<>;

### What to do about it?

In order to deploy the systemvm's on the kvm cluster end user has to update the database

Provide an option to force remove the systemvm which are struck in expunging state or introduce a zone level setting which can specify the cluster for the systemvm deployment

Comienza rastreando el fallo a través de RemoteHostEndPoint.java, CloudStackPrimaryDataStoreDriverImpl.java, VolumeServiceImpl.java y VolumeOrchestrator.java, usando el registro del agente desconectado como punto de entrada. Reproduce el escenario de VMware/KVM con dos clústeres e inspecciona la ruta de destroy y expunge. La tarea estará terminada cuando las system VMs puedan eliminarse o expungirse sin actualizar manualmente vm_instance, permitiendo el despliegue en el clúster KVM.
