Elasticsearch has recently added scaled_float as an option for storing floating point numbers. The scaled floats are stored internally as longs, which means they can take advantage of the integer compression in Lucene. See elastic/elasticsearch#19264 for details. The PR moves all percentages to scaled floats. In our `fields.yml` we assume a default scaling factor of 1000, which should work well for our percentages (values between 0 and 1). This scaling factor can also be set to a different value in `fields.yml`.
