CoreOS Metadata

This is a small utility, typically used in conjunction with Ignition, which reads metadata from a given cloud-provider and applies it to the system. This can include adding SSH keys and writing cloud-specific attributes into an environment file. This file can then be consumed by systemd service units via EnvironmentFile=.
