Read files cloud-config.d in alphanumeric order, then cloud-config.yml `ros config` writes to cloud-config.yml (and cloud-config.d/private.yml - only private keys) Add (c *CloudConfig) Save() method, use it to save the changed config Read and apply metadata as part of LoadConfig() Simplify ros config export logic
