Perform some cleanup before plugin unregister

Hi _vladi_ and laurentsd,

Is there any way to get an indication that plugin is going to be unregistered before, so that we can do some clean up?

Suppose, we have a logs created for the plugin which we have registered.

During unregister we want to clean the plugin's log directory.

Note: Register/Unregister is done using the extension-registration script provided in SDK.

Can you please help?

Thanks
