test_data: Simplify default configuration for local testing

Browse Source 
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.

For local testing data kept in test_data/cloud-init/ubuntu/local folder.
This contains minimum configuration data for user to test it locally.
Script assigns default IP address using "network-config" details
with --net "tap=" option. The default network interface will be "ens4".
