[GEO] Add optional left/right parameter to GeoJSON

This feature adds an optional orientation parameter to the GeoJSON document and geo_shape mapping enabling users to explicitly define how they want Elasticsearch to interpret vertex ordering.  The default uses the right-hand rule (counterclockwise for outer ring, clockwise for inner ring) complying with OGC Simple Feature Access standards. The parameter can be explicitly specified for an entire index using the geo_shape mapping by adding "orientation":{"left"|"right"|"cw"|"ccw"|"clockwise"|"counterclockwise"} and/or overridden on each insert by adding the same parameter to the GeoJSON document.

closes #8764
I wonder if this should be an enum instead of a boolean value? I don't feel too strongly about this but it may help when users see the method signature in the Java API. With boolean they may not see that these constants exist, but with the Enum it is pretty obvious.
