CLOUDSTACK-9900: Fix high CPU deviation issues seen in metrics view
HostStats returns cpu usage in percentage while memory usage in bytes.
This fixes a regression in maximum CPU usage deviation that did not
assume the values to be in percentage and multiple the final ratios
with 100 which leads to 100x the actual deviation value.

> High CPU deviation (100-400%) is seen in the metrics view. The regression was
> caused becase HostStats returns CPU usage in percentage and memory usage in
> bytes, while the deviation calculation method did not assume that passed
> values are in percentage and multiples the ratios by 100 resulting in 100x
> the actual values.
