The updated Bender version is configurable regarding the mode in which to run
the Intel HWP plugin. This can now be controlled via the new run option
'--bender-intel-hwp-mode' (only when running on NOVA). The option knows 4 valid
values 'off', 'performance', 'balanced', and 'power_saving'. When running on
NOVA, the default value applied by the run tool is 'performance'. when running
on any other kernel, the default value of Bender ('off') is used. Therefore,
when not setting the new '--bender-intel-hwp-mode' flag, the behavior is the
same as before this commit.
