feat: created python script to extract env vars and convert to ini files

this will be used to allow config files to be 100% managed via docker env vars
created unit tests to cover script
added gitignore to ensure no python relate junk ends up in the repo

+#   Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control.
