Root volume resize performed on scaling service offering

[rohityadavcloud]

When service offering of a (stopped) VM is changed using the scaleVirtualMachine API, its root disk get resized. In case the primary storage pool don't have enough capacity, the operation will fail. However, changeServiceForVirtualMachine API can allow changing offering for a stopped VM and won't try to resize the root disks.

The issue was introduced recently, and exists in 4.11 but not in 4.9: a30a31c#diff-0a1cd9df984252594918eec5acfed08cR1121 /cc @mike-tutkowski

@rhtyd can you expand on this? is it still an issue? what is the scenario and required outcome? should scaleVirtualMachine or changeServiceForVirtualMachine change?
I don't think we can expect @mike-tutkowski to work on it soon, so probably move a future milestone...

@khos2ow Perhaps you can investigate this?

@khos2ow @mike-tutkowski @syed moving this to 4.15 soon (and yes that is a thread)
