Retrieve the list of all defined Erp Connectors (not Connections, that's another list)
[MDOProviderPlugin("ErpConnectors")] public class ErpConnectors : LiteralsOnlyBase, ISoListProvider, ISoList, IPlugin
Implementation relies on the ErpConnectorProvider archivelist, and simply reformats its data.

public const string ProviderName = "ErpConnectors"
protected override void AddItems()
