Expose attributes for vegetation and groundwater exchange in attribute forms and attribute tables

[leendertvanwolfswinkel]

• [ ] Add the following fields to the attribute forms of the layers Pipe, Channel and Manhole
• exchange_thickness = Column(Float)
• hydraulic_conductivity_in = Column(Float)
• hydraulic_conductivity_out = Column(Float)
• [ ] Add the field vegetation_drag_settings_id (integer) to the attribute forms of the layer Global settings
• [ ] All these fields should be nullable and are not required inputs
• [ ] These same fields are currently hidden in the attribute table; please un-hide them

Hi @ldebek I have tested this and I have the following feedback / additional wishes:

• [ ] Saving/loading test fails for Manhole and Pipe. What I did:
• Edit a manhole, fill in the groundwater exchange attributes, save changes, stop editing, check in attribute table if changes have been saved. Save to spatialite, load from spatialite. Now the groundwater exchange attributes are empty for all manholes
• Same for pipe, same result
• Same for channel -> this works as it should
• [ ] Channel: groundwater exchange fields are still hidden in attribute table
• [ ] Add units to the labels:
• Exchange thickness [m]
• Hydraulic conductivity in [m/d]
• Hydraulic conductivty out [m/d]
• [ ] Please rename the new group in the attribute form to 'Groundwater exchange'
• [ ] Also add the groundwater exchange attributes to the 'starting manhole' and 'ending manhole' tabs of the Pipe attribute form
