Most of the functionality don' work in this mode, it just
applies the settings, no rollback possible.
Disable daemon by setting 'daemon = 0' in /etc/tuned/tuned-main.conf
This settings can be overridden if running tuned with '-d' command line
option. In such case daemon mode will be used.

In this way only the installed profiles are described in the installed
manual pages. I.e. base profiles are now described in the tuned-profiles.7
manual page and profiles for the Project Atomic are now described
in the tuned-profiles-atomic.7 manual page. Simalarly for the SAP and
compat profiles.

This policy sets the link to the second lowest power
state (PARTIAL) when there is no I/O on the disk. This
mode is designed to allow transitions in link power states
(for example during times of intermittent heavy I/O and
idle I/O) with as small impact on performance as possible.
This may save significant amount of power in idle periods
of the link, especially on laptops. E.g. on x240 the average
AC power consumption dropped from approx. 5 W to only 2.5 W.

This improves responsiveness of Tuned in Python 2 interpreter with applied
patch for rhbz#917709. There is new global config parameter "sleep_interval"
which can control the polling. By default it is set to 1 second which is
still much better than 50 ms (on unpatched intepreter). Also the overhead
of the main thread was lowered if the dynamic tuning is disabled. The
dynamic tuning update interval is still controlled by the "update_interval"
global config parameter, but it has to be multiply of the "sleep_interval".
