Elasticsearch 5.0

[matthewdu]

The api for cat index changed in ES 5.0. By default it no longer returns a json.

https://github.com/omc/searchyll/blob/master/lib/searchyll/indexer.rb#L136
The endpoint here needs to be changed to

/_cat/indices?h=index&format=json

Thanks Matthew, nice catch! It looks like we're currently relying on the Content-type: application/json header, which is no longer respected for this purpose, in favor of the Accept header or the query string parameter. I'll go ahead and get this fixed up in a jiffy.

Great. Accept header is even better.
