[OAPIF provider] Add support for edition capabilities (OGC API Featur…

…es Part 4)

- Issues OPTIONS on /collections/{coll_id} and collections/{coll_id}/{feature_id}
  endpoints to check server capabilities
- Add support for addFeature() through POST /collections/{coll_id} endpoint
- Add support for changeGeometryValues()/changeAttributeValues() through
  PUT /collections/{coll_id}/{feature_id} endpoint.
  Or through PATCH /collections/{coll_id}/{feature_id} with just the
  updated subset, if available
- Add support for deleteFeatures() through
  DELETE /collections/{coll_id}/{feature_id} endpoint.
- For POST/PUT/PATCH, takes into account Part 2 (CRS support) when implemented
  by the server.
