SPDX license list import Rake task

GitLab provides a Rake task for uploading a fresh copy of the SPDX license list to a GitLab instance. This list is needed for matching the names of License approval policies.

To import a fresh copy of the PDX license list, run:

# omnibus-gitlab
sudo gitlab-rake gitlab:spdx:import

# source installations
bundle exec rake gitlab:spdx:import RAILS_ENV=production

To perform this task in the offline environment, an outbound connection to licenses.json should be allowed.
