Include cloud-init code in library

[pploegaert]

In ci_constants/vm_handler the following lines refer to an external link:
we should include these in our own library:

    CLOUD_INIT_DATA = {
        'script_loc': 'https://raw.githubusercontent.com/kinvaris/cloud-init/master/create-config-drive',
        'script_dest': '/tmp/cloud_init_script.sh',
        'user-data_loc': '/tmp/user-data-migrate-test',
        'config_dest': '/tmp/cloud-init-config-migrate-test'
    }

The script_loc refers to a location not within our control ...

Its a fork towards some repo. I currently forked it too because Kinvaris has left.

Feel free to add it to the fileserver or something and update the config location accordingly.
