Convert GeoData for elasticsearch 5 update
Once elasticsearch 5 is shipped out the configuration of geo_point
fields slightly changes. It will no longer be necessary to specify what
type of input will be provided, instead the field just accepts all
possible inputs and figures out what was provided at index time.
Additionally changes integers 1/0 representing a boolean to true/false,
as 1/0 is deprecated in 5.x.
Don't merge this until after the elasticsearch 5 upgrade. Indices
created before we switch to es 5 need this config in the mapping.
