tools: Add cloud-id command line utility

Add a quick cloud lookup utility in order to more easily determine
the cloud on which an instance is running.

The utility parses standardized attributes from
/run/cloud-init/instance-data.json to print the canonical cloud-id
for the instance. It uses known region maps if necessary to determine
on which specific cloud the instance is running.

Examples:
aws, aws-gov, aws-china, rackspace, azure-china, lxd, openstack, unknown
