feat: Application is dockerized

[myhailo-chernyshov-rg]

Description

This PR is addressed to make the converter platform-independent.
To perform it, Dockerfile is written, the files that should not be included into Docker image are specified in .dockerignore.
All base requirements are installed during application installation.

Usage instructions

1. Build the image:

docker build -t cc2olx .

2. Run the conversion command in a container by mounting passed argument path directories/files and passing the corresponding arguments to the script:

docker run --rm -v /input/file/path/cc_course_dump.imscc:/data/input/cc_course_dump.imscc -v /output/file/path/output_dir:/data/output/ cc2olx -r zip -i /data/input/cc_course_dump.imscc -o /data/output/edx_dump

It will convert Common Cartridge dump from /input/file/path/cc_course_dump.imscc and save the OLX in /output/file/path/output_dir/edx_dump.zip file.

Deadline

"None"
