tuned(8) realtime-virtual-{host|guest} profiles set Kernel and
KVM module parameters via script.sh plugin. These parameters are
to be verified in a verify() function, invoked by tuned-adm verify
command.
This patch updates verify() functions to validate KVM module
parameters.
It moves kernel parameters to the tuned.conf file under the
[sysfs] & [sysctl] plugin sections. And removes call to
disable_ksm function, no longer required.
