Change default directories to home path
Created by: J3FALL
Currently, at least in 2 modules (logging and chain import/export), we have the following logic:
- If a file/directory path is given, then use it for write/load operations
- Otherwise use default paths (that is given as 'project_root/.../default_directory/etc.)
However, for non-developers of FEDOT it is not a convenient way to check logs or files. Therefore, the solution can be using HOME directory instead of the current implementation. The example of how it can be implemented is here: https://stackoverflow.com/questions/4028904/how-to-get-the-home-directory-in-python
