Dry weather flow: attribute forms and handlers

[leendertvanwolfswinkel]

In the new database schema, users schematise dry weather flow (DWF), i.e. wastewater produced by households or industry, using these layers:

• dry_weather_flow: A location from which the DWF originates (polygon geometry)
• dry_weather_flow_map: A mapping from the dry_weather_flow feature to a connection_node feature
• dry_weather_flow_distribution: Contains one or more time series that define the intra-day distribution of DWF. Referred to from the dry_weather_flow in the dry_weather_flow.dry_weather_flow_distribution_id column

The dry weather flow layer is migrated from what was formerly the v2_surface or v2_impervious_surface layer
The dry weather flow map layer is migrated from what was formerly the v2_surface_map or v2_impervious_surface_map layer
