This commit contains a fairly large diff for a fairly small change: moving the `config/common` directory to `host/base` to better reflect its intended use, and promoting `config/service` to the root directory. These changes unlock some improvements in `coreos-home-server-update` processes, which will (assuming `/etc/coreos-home-server/base` exists) keep host-wide systemd services in sync in addition to service-specific ones. Changes have been make to the `Makefile` and a few other places where `config/common` was referenced, but most of this work is renames that are not intended to break compatibility with new or running servers.
