> 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.
