[TEST] Random dynamic templates.

This change randomly indexes the _id field and randomizes field data formats
and loading.

Close #5834
[TESTS] Don't randomize mappings in SimpleValidateQueryTests.

This test relies on the fact that the _id field is not indexed.
Remove RootMapper.validate and validate the routing key up-front.

RootMapper.validate was only used by the routing field mapper, which makes
buggy assumptions about how fields are indexed. For example, it assumes that
the index representation of a field is the same as its external representation.

Close #5844
Made it mandatory to specify IndicesOptions when calling MetaData#concreteIndices

Removed MetaData#concreteIndices variations that didn't require an IndicesOptions argument. Every caller should specify how indices should be resolved to concrete indices based on the indices options argument.

Update geo-shape-type documentation

Update `geo-shape-type.asciidoc` to include all `GeoShapeType`s supported by the `org.elasticsearch.common.geo.builders.ShapeBuilder`.

Changes include:

1. A tabular mapping of GeoJSON types to Elasticsearch types
2. Listing all types, with brief examples, for all support Elasticsearch types
3. Putting non-standard types to the bottom (really just moving Envelope to the bottom)
4. Linking to all GeoJSON types.
5. Adding whitespace around tightly nested arrays (particularly `multipolygon`) for readability
Removed mention of Spatial4J and JTS requirement

AFAIK, on 1.0 at least (and later), those libraries are included.

Improve 404 on missing scroll id
This relates to #6040, the fix is twofold, first, not handling missing context specifically in the search code, but behave the same as we do in non scroll search, where if all the shards failed, raise an exception. The second is to apply this logic in both scroll cases.

s/boost_factor/boost in custom_filters_score doc

I may be wrong but I think custom_filters_score used boost rather than boost factor?
