Enes Cakir 6c4746e95a Fix Vm::Nexus#destroy to not violate strand leases 
Previously, Vm::Nexus#destroy ran:

```ruby
strand.children.select { it.prog == "Aws::Instance" }.each { it.destroy }
```

This is not safe as there could be an existing lease for Aws::Instance children.

@jeremy fixed a similar issue at 773562ebc.

Fix this by VM increments the destroy semaphore instead of destroying directly.
Aws::Instance will pop out if the destroy semaphore is incremented.

I didn’t add semaphore :destroy to Aws::Instance, since one of its
subjects is :vm, which already has a destroy semaphore.
