    Fix the NPE tht was being caught by the executeRequest() method.
       - The LibvirtUtilitiesHelper should have been injected, but it did not 
work on the Agent side.
         Due to that, when sending a StartCommand we were experiencing NPE, 
which made impossible to get SSVM/CPVM started.
       - The LibvirtUtilitiesHelper class is now being instantiated withing the 
LibvirtComputingResource
