What is the current behavior?

TapChangerAutomationSystemBuilder has only one setter side taking anTransformerSide enum as argument.
This setting work with Groovy DSL supplier but the DynawoModelsSupplier cannot use it since the type of each property has to be specified with an PropertyType.

What is the new behavior (if this is a feature change)?
Since the TransformerSideenum is rather specific, we add a new TapChangerAutomationSystemBuilder::side with String argument.
