    This refers to cluster level setting, admins should be allowed to override 
this at the cluster level. Please change this to ConfigKey.Scope.Cluster.


> Allow starting VMs regardless of cpu/memory cluster.disablethreshold setting

> VM deployments are not allowed on clusters where resource (cpu/memory) 
> allocation has exceeded the cluster disabled thresholds. The same policy also 
> gets applied in case of start VM if last host where the VM was running 
> doesn't have enough capacity and a new host is picked up. In certain 
> scenarios this can be restrictive and despite having capacity, the VM cannot 
> be started.
> This improvement is to provide administrator an option to disable/enable 
> cluster threshold enforcement during start of a stopped VM as long as 
> sufficient capacity is available.
