 In harbormaster it is possible to upload build artifacts and associate
 them with each build, for example we could upload the user manual for each
 build or even binaries. I am not sure what would be useful. One use case
 might be checking the rendering of the user guide when it is modified.

 The idea is to write a small utility program which uploads suitable
 artifacts and then add an extra build step
 to the relevant build plans which calls this program. The utility doesn't
 have to be in-tree as it can be installed in the environment.

 Some more information:

 * There are some bindings to the phabricator API in [https://github.com
 /haskell-infra/arc-lite arc-lite]
 * The relevant API methods are `file.allocate`, `file.upload` and
 `harbormaster.createartifact`
 * `file.allocate` allows you to specify a time to delete a file, this
 would be good to avoid consuming lots
     of storage for builds.
 * Artifacts appear in the "artifacts" tab
