Way faster ansible-galaxy handling with some parallelization and parsing

ur.sh

#
# ./ur [ansible-galaxy dependency name] -> install the 1 dependency
# ./ur playbooks/play.yml -> parse and install dependencies found in playbook
# ./ur -> find all dependencies in ansible-requirements.yml and install them in parallel
