// Package updater handles requests to update the agent.
//
// Requests are assumed to be two-phase where the phases consist of a 'download'
// followed by an 'update'. Either of these steps may fail.
// The agent is responsible for, on download, correctly downloading the
// referenced file and validating it against the provided checksum. However,
// the actual 'update' component is handled by signaling a watching process via
// exit code.
