JIRA issue

https://jira.camptocamp.com/browse/GSLUX-737

Description

Export drawn feature as gpx, kml and shapefile + fix export gpx for circle and polygon (does not work in prod).
Export gpx and kml does not call api anymore.

NB. use chrome plugin for CORS policy when exporting to shapefile (you need v3 running on localhost:8080)

Thanks for the clean architecture and the unit tests @AlitaBernachot!

PR LGTM, only thing I noticed testing is that production also exports feature properties in a <ExtendedData> tag within KML, not shapefile though. So I don't know if it's relevant.

There are ExtendedData in kml files exported by v3 because v3 is setting some properties on ol layers (__editable__, __refreshProfile__, __map_id__, __selected__, display_order, name, isLabel, opacity, shape, ...). It looks like these are properties made for the Controller more than for the kml export functionality. Maybe there is a functionality to import kml and in that case it will be relevant, but for now I am just ignoring these prop.

@tkohr after checking with the client, it is possible to import kml but you need to login first and use MyMaps. Since this is related to MyMaps functionality, I suggest to handle this during the dev for MyMaps (https://camptocamp.atlassian.net/browse/GSLUX-710).

@tkohr just tested adding random custom property to the feature (eg. feature.set('__my_totoprop__', 'Toto')), ol kml writer automatically creates <ExtendedData> with the custom prop <Data name="__my_totoprop__"><value>Toto</value></Data> in the kml, so it should be easy in the future to add all the custom props related to mymaps (editable, refreshProfile, map_id, selected)
