980f5e2187 refactor(server): Move package source management logic to server
Introduces three new types representing each of the possible package
sources and moves the logic for specifying the package source to the
server.

Concrete changes:

* Determining whether a specified git reference is a commit vs. a
  branch/tag is now done in the server, and is done more precisely by
  using a regular expression.

* Package sources now have a new `CacheKey` function which can be used
  to retrieve a key under which a build manifest can be cached *if*
  the package source is not a moving target (i.e. a full git commit
  hash of either nixpkgs or a private repository).

  This function is not yet used.

* Users *must* now specify a package source, Nixery no longer defaults
  to anything and will fail to launch if no source is configured.

32b9b5099e feat(server): Add configuration option for Nix build timeouts
Adds a NIX_TIMEOUT environment variable which can be set to a number
of seconds that is the maximum allowed time each Nix builder can run.

By default this is set to 60 seconds, which should be plenty for most
use-cases as Nixery is not expected to be performing builds of
uncached binaries in most production cases.

Currently the errors Nix throws on a build timeout are not separated
from other types of errors, meaning that users will see a generic 500
server error in case of a timeout.

This fixes #47

9a95c4124f fix(server): Sort requested packages in image name & spec
Before this change, Nixery would pass on the image name unmodified to
Nix which would lead it to cache-bust the manifest and configuration
layers for images that are content-identical but have different
package ordering.

This fixes #38.

3b65fc8c72 feat(server): add iana-etc and cacert to the shell convenience package
These probably should be part of every container image by default, but
adding it to the "shell" convenience name probably is our best bet for
now.

cf227c153f feat(builder): Implement build cache for manifests & layers
Implements a cache that keeps track of:

a) Manifests that have already been built (for up to 6 hours)
b) Layers that have already been seen (and uploaded to GCS)

This significantly speeds up response times for images that are full
or partial matches with previous images served by an instance.

This module is going to get more complex as the implementation of #32
progresses.
