Ghost/ghost/data-generator/lib/importers/MembersLabelsImporter.js
Sam Lord 4ff467794f Entirely rewrote data generator to simplify codebase
refs: https://github.com/TryGhost/DevOps/issues/11

This is a pretty huge commit, but the relevant points are:
* Each importer no longer needs to be passed a set of data, it just gets the data it needs
* Each importer specifies its dependencies, so that the order of import can be determined at runtime using a topological sort
* The main data generator function can just tell each importer to import the data it has

This makes working on the data generator much easier.

Some other benefits are:
* Batched importing, massively speeding up the whole process
* `--tables` to set the exact tables you want to import, and specify the quantity of each
