esberglu 8a67fcd1c2 PowerVM: Add proc_units_factor conf option
This introduces a new PowerVM conf option, proc_units_factor, which can
range from 0.05 to 1.0 and will default to 0.1. It is used to calculate
the physical processing power to assign per vCPU, where 1.0 is a whole
physical processor and 0.05 is 1/20th of a physical processor.

Introduces the ``powervm`` configuration group which contains the
``proc_units_factor`` configuration option. This allows the operator to
specify the physical processing power to assign per vCPU.

Previously the PowerVM driver would default to 0.5 physical processors per
vCPU, which is the default from the pypowervm library. The default will now
be 0.1 physical processors per vCPU, from the ``proc_units_factor``
configuration option in the ``powervm`` configuration group.
