Add optional property "cloud_info" for VMIs

This commit introduces a new optional property for all VMIPushItems
named `VMICloudInformation` which stores the cloud's provider name and
account alias into it.

The goal of this change is to be able to parse the patched `clouds.json`
with this new property, which was instroduced in
pubtools-marketplacesvm#71, allowing the DeleteTask to have a more
reliable way to retrieve the provider/account information.
