Subject: migrating config

This deploy logic is primarily based on hxchn's deploy lib [1], with some
slight modifications to make it work with my setup. Everything seems to work
fine for now.

However, I am unsure about the usage of niv — the config doesn't seem to gain
much from it, apart from (some) additional complexity.
