CLOUDSTACK-2987 Ensure XStools to be there in template inorder to enable
dynamic scaling of vm
CLOUDSTACK-3042 - handle Scaling up of vm memory/CPU based on the presence of
XS tools in the template
This also takes care of updation of VM after XS tools are installed in the vm
and set memory values accordingly to support dynamic scaling after stop start
of VM

>
> XS tools need to be installed on the guest vm for Xenserver for memory
> dynamic scaling and over provisioning to work.
> XStools contain baloon drivers that are required to dynamically manipulate
> the memory attributes (dynamic max/min). If they are altered at run time
> without these tools, it can lead to unstable behavior for vm and potential
> crash. Both for memory dynamic scaling and over provisioning this is
> required.
> So we need to be able to ensure whether xstools are installed on the template
> based on the user inputs while registering the template and use the same to
> set different memory/cpu values to make dynamic scaling work.
