IMP: add multiple Improvements

* add new kernel module detection (enable & listing)  with detection of monolithic kernel
* change way to detect if file system type is disabled
* add global IS_CONTAINER variable
* disable test for 3.4.x to be consistent with others
* add cli options to override configuration loglevel
