[esArchiver] support archiving of data streams

[neptunian]

When trying to write a functional test for Metrics UI, I archived the data specifying .ds-metrics-*. This archives the correct indices, though it does not archive the associated data stream. When the index is recreated using esArchiver load the indices are created without the relative data stream. This is a problem because the view I need to test in the metrics UI queries with the index pattern metrics-*, metricbeat-* which matches the data stream name so no data is returned.

I would expect that something like node scripts/es_archiver save metrics-8.0.0 would detect that the index is an alias controlled by a data stream, archive the necessary template, and then archive all the docs from the data stream associated with the metrics-8.0.0 alias so that the docs could be indexed by a newly created data stream on load.
