UI support for the scaleSystemVm API

[gruckbit]

Description

ACS has the scaleSystemVm API that allows scaling system VMs. However, currently the API is not accessible through the graphical interface for KVM. Thus, the graphical interface has been extended to allow the execution of this API.

How Has This Been Tested?

The global setting enable.dynamic.scale.vm was set to True, then the system VM template's Dynamically scalable option was also set to True. Finally, new system offerings were registered to verify the form's listing behavior, showing only offers greater than or equal to the current offer. Lastly, the service offering change was performed both for running and stopped VMs.

Before:

virsh dumpxml 4 | grep "memory unit" -A 2
  <memory unit='KiB'>524288</memory>
  <currentMemory unit='KiB'>524288</currentMemory>
  <vcpu placement='static' current='1'>4</vcpu>

After:

virsh dumpxml 5 | grep "memory unit" -A 2
  <memory unit='KiB'>2097152</memory>
  <currentMemory unit='KiB'>2097152</currentMemory>
  <vcpu placement='static' current='2'>4</vcpu>

Nit: mixing &&/|| without parens around the whole expression is a bit hard to scan, even though the added parens around the hypervisor check are correct. Wrapping the full condition in parens would make the intent clearer at a glance.
