Legacy behaviour is mostly retained. The most notable change in behaviour is that invoking `resin deploy` without options is now allowed (see help string how it behaves). In this commit there are also the following notable changes: - Deploy/Build are promoted to primary commands - Extracts QEMU-related code to a new file - Adds a utility file to retrieve the CLI version and its parts - Adds a helper that can be used to manipulate display on capable clients - Declares several new dependencies. Most are already indirectly installed via some dependency Change-Type: minor
