OS tools refactor:

- make udev, runlevel, memory and wget separate files
- rename os_utils to os_tools and move it to test_tools
- remove ModuleRemoveMethod and set modprobe as default
- fix regex in is_kernel_module_loaded method
- remove get_sys_block_path
- move get_block_device_names method to disk tools
