Files were generated with the `thor api:generate:spec --force --verbose --crawl` command,
and based on the 0.90 branch (elasticsearch/elasticsearch@5ec4064).
The generator will parse the Elasticsearch *.java source files,
extract information about REST API endpoints (URLs, HTTP methods, URL parameters, etc),
and create a skeleton of the JSON API specification file for each endpoint.
