bdce7eb69d add new enterprise-storage profile 
Starts out as a clone of throughput-performance profile, but takes the
additional steps to disable barriers on data volumes and increase
readahead values.

927529c1cc further throughput-performance profile tweaks 
- don't set pid_max by default, as it can be highly dependent on cpu
  count (and architecture, to some extent)
- add commented out vm.dirty_background_ratio param, which we may or may
  not set sometime in the future, but its also there now for people to
  enable w/relative ease.

3be9255472 governors: prefer cpuspeed, restore for each CPU 
Added verifications, whether tuned cpu supports scaling.

Previous governor settings are saved and reverted separately for each
CPU.

If 'cpuspeed' is installed, CPU governor is set by changing it's
settings. If not, governor is set directly through sysfs and a message
suggesting installation of 'cpuspeed' is shown.

Updated profiles:
- laptop-batery-powersave
- latency-performance
- throughput-performance

Missing VAR_SUBSYS_KTUNE variable in ktune.sh scripts prevented these
scripts to run stop() when disabling profile.

 - laptop-ac-powersave
 - server-powersave
 - spindown-disk
