confDB2: Use 'PublicToolHandle', 'PrivateToolHandle' and 'ServiceHandle' instead of GaudiHandleBase as cpp_type
Hi @clemenci,
to first order, this MR solves the problem with confDB2 I mentioned in yesterday's Gaudi-meeting. The method PropertyBase.pythonPropertyClassName()
returns the information I need. But to allow for the detailed type-checking you implemented as ComponentSemantics here, more work is needed to get also the payload-type of the handle.
