Index templates are ignored

[markwalkom]

We were testing this out today and noticed that, despite having index templates available, these weren't used when stream2es created the index at start.
If we manually create the index via a curl and then populate it with stream2es, it obviously works.

Is this intended behaviour due to the --settings being "null", or are we missing something?

@markwalkom that's because stream2es defines the mapping on its own
