ci: Move CI related test data to separate folder

Script `create-cloud-init.sh" uses the same cloud init data as the the CI
but this means it is somewhat overloaded with unhelpful network configuration
entries and scripts that are only needed for the CI.

CI related data moved to test_data/cloud-init/ubuntu/ci folder.

Fixes: #4773
