[Question\Sugestion] Support WKT point conversion to geo_point type

[4nonym0us]

Having WKT POINT support only for geo_shape and not for geo_point is a bit confusing because WKT specification has GeoPoint representation.

Would't it be good to have an option to use WKT's point syntax POINT (X, Y) for geo_point for consistency as support even for more complex WKT primitives and multipart geometries is already present for geo_shape?

I'm working on this issue.
@imotov, geo_point field can actually contain an array of geo_point.
Does it mean we need to support something like WKT's MULTIPOINT? Or simply supporting POINT is enough?

[imotov]

@Hohol I think just point should be enough to start with. If you use WellKnownText parser, you can try parsing the string as WKT and then throw an exception if it is not a Point. We can expand it later to MultiPoints and other geometries if there is a need.
