This is generated whenever a data resource cannot be built because it is missing data for at least one layer. Using a custom exception type here enables a few new features:
1. A single build process is now able to request missing data from all the layers that need it. Previously it would only request from the first missing layer and would then give up. This resulted in the user/application having to issue the build command multiple times rather than just once, until all layers had been requested.
2. GET /arbitrary/{service}/{name} will now block the response and retry in the background until the data arrives. This allows it to be used synchronously. Note: we'll need to add a timeout.
3. Loading a website via GET /site/{name} will avoid adding to the failed builds queue when a MissingDataException is thrown, which allows it to be quickly retried. The interface already auto refreshes, allowing the site to load as soon as it's available.
