Unique name for instrument logger

[jenshnielsen]

This ensures that each instrument will have it's own logger so that messages can easily be filtered by instrument instance

An instrument will have a logger with a name of the form module.path.to.instrument.classname-instancename and in the same way a channel will have a logger with a name of the form module.path.to.instrument.classname-instancename.channelclassname-channelinstancename

If we go that way there should be some tests added

This is now replaced by https://github.com/QCoDeS/Qcodes/pull/5297 which will ensure that the instrument_name is an extra attribute on the logrecord from the instrument LoggerAdapter
