Ubuntu Cloud Image

This is used to find the latest Ubuntu image information for
clouds. The following clouds are supported:

• Amazon Web Services (aws)
• Amazon Web Services China (aws-cn)
• Amazon Web Services GovCloud (aws-govcloud)
• Microsoft Azure (azure)
• Google Compute Engine (gce)
• Kernel-based Virtual Machine (kvm)
• Linux Containers (lxc)
• Metal as a Service (MAAS) Version 2 (maasv2)
• Metal as a Service (MAAS) Version 3 (maas)

The program uses the streams output provided by various clouds to
determine the latest images available on clouds. Where they are
supported this includes the latest daily, minimal, and daily
minimal images as well. Daily and minimal images are enabled with
the --daily and --minimal flags.

The output is the full JSON output from streams providing details
about the requested image. If no image matches the specific filter
then an empty JSON array is printed.
