feat(ops/modules): Add module for running Nixery

This sets up a very simple Nixery instance with some things lacking:

* no support for garbage-collecting image fragments (yet)
* no popularity setup

The plan is to use this to get the ball rolling on a separate
domain (e.g. images.tvl.fyi), iron things out and then look into
flipping over nixery.dev
