Due to Python 2 EOL I need to pick new language for
uploader tools. Instead of Python 3 I choose Go,
because I'm working with this language almost three
years and a half.
Python 2 CLI app moved to legacy/python2 branch and
will be supported due 01 January 2020.
Old shell scripts are still in legacy/shell branch and
doesn't work ATM. I will not fix them, they're keeped in
repository for historical reasons only.
