CSC should handle Ansible variables passed via command line

After resolving the issue https://gitlab.ics.muni.cz/muni-kypo-csc/cyber-sandbox-creator/-/issues/74, CSC can now generate sandboxes for locally deployed games, such as Junior hacker.

The only thing that must be added manually to the generated Vagrantfile is the line for processing Ansible args, such as ansible.raw_arguments = Shellwords.shellsplit(ENV['ANSIBLE_ARGS']) if ENV['ANSIBLE_ARGS']. We should discuss if CSC can be extended to handle this automatically.
