We create the /etc/modprobe.d/kvm.rt.tuned.conf file at
every boot. However, there's nothing that guarantees that
the kvm module will be loaded after tuned. Indeed, it's
possible to reproduce a race where the kvm module is loaded
before tuned. When this happens, the kvm module will be
loaded with incorrect parameters as the kvm.rt.tuned.conf
file doesn't exist.
The solution to this problem is to create the kvm.rt.tuned.conf
file only if it doesn't exist and delete it when changing
profiles.

Added new tuned-adm functionality 'profile_info'. It has optional parameter
'profile_name'. If called without parameter, active profile is used.
It outputs name of the profile it is querying, profile summary, and profile
description. If there is no profile summary or description available it
outputs empty string(s).
Extended tuned-adm 'list' functionality. It now displays profile summary
in the list (if available).
Added summary to profiles.
Extended D-Bus API to support the new feature and for better Cockpit support:
- Added 'profile_info' method. It gets profile_name argument and it queries
the requested profile for information. If profile_name is empty string it
queries the active/selected profile. It returns tuple of the following
format (status, profile_name, summary, description), where status is
boolean. If it is False, the query mechanism failed and the other fields
don't contain valid data
- Added 'profiles2' method. It's extension of 'profiles' method. It returns
list of tuples. Tuples have following format:
(profile_name, profile_summary)
