convenience function for finding any existing data providers that match "providerKey"
Necessary because [] map operator will create a QgsProviderMetadata instance. Also you cannot use the map [] operator in const members for that very reason. So there needs to be a convenient way to find a data provider without accidentally adding a null meta data item to the metadata map.
