fix: Use tuned files instead of using it as a module

[richm]

The previous version of the kernel_settings role used tuned as a python library, and had a kernel_settings module which was a wrapper around this code. However, tuned version 2.23 has changed its internal API and it is no longer possible to use it as a python library. Instead, the kernel_settings role has been refactored to read/write tuned config files, and let the tuned daemon manage the settings.

In addition, tuned 2.23 changed the location of the profile directory, so the kernel_settings role will now determine the location of the profile directory depending on the tuned version.

The old kernel_settings module is removed, along with all of the python unit testing code.

A new kernel_settings_get_config module has been created which will simply parse and return the given config file as a dict.
