Deprecated field [ignore_unmapped] used, replaced by [unmapped_type]

[kadishmal]

Since Kibana 4.5 requires 2.3, I think it is safe to refactor migrate_config.js file and replace the deprecated ignore_unmapped parameter with unmapped_type which is deprecated since 2.0.

This is already fixed in master

This still seems to be appearing in Kibana 4.6.1. I see the following deprecation warning in Elasticsearch constantly:

[2016-10-30 22:48:27,670][DEBUG][deprecation.common       ] Deprecated field [ignore_unmapped] used, replaced by [unmapped_type]

When I turn on slowlogs with a 0s threshold, I see these queries:

[2016-10-30 22:48:27,670][WARN ][index.search.slowlog.query] [proliant] [.kibana][0] took[102.4micros], took_millis[0], types[config], stats[], search_type[QUERY_AND_FETCH], total_shards[1], source[{"size":1000,"sort":[{"buildNum":{"order":"desc","ignore_unmapped":true}}]}], extra_source[], 

What could be the cause here? Failed migration of config?

@joshuar looks like this only got into 5.x #6463

The original PR has been backported for 4.7, so assuming it doesn't get reverted during testing, it should also go out with that release.
