Positibility to set application name for taps

Is your feature request related to a problem? Please describe.
Would be helpful, to be able to set the application name, or at least append it, so that it is not just pipelinewise. When running multiple taps, it would be helpful, to have this opportunity to distinguish between multiple.

Describe the solution you'd like
Another configuration parameter besides the existing connection parameters, named application_name or appname.
