pathlib - OS agnostic Python methods for handling configuration files.

[aiqc]

Difficulty: ★★☆☆☆ (cross OS testing)

Background

AIQC works on Mac, Linux, Windows. Managing local files can be a pain across different operating systems as they don't all use bash or they use 'backward/no trailing' slash versus 'forward/trailing' slash.

Problem

In some cases, Python-based OS-agnostic methods like os.makedirs() are used. However, in other situations, we are still using cmd_file_create = 'echo "test" >> ' + app_dir + file_name.
The Python methods were written for this use case, so we should use them!

Solution

Go through the lines of code related to configuration file and database creation and convert manual sys commands to Python based commands wherever possible. Decide if we should switch to using: https://docs.python.org/3/library/pathlib.html

Must test any changes across Windows, Mac, and Linux.
