Introduce karton debug

[nazywam]

The karton debug mode helps with developing karton services while connected to the production karton network. It does that by:

• appending a random suffix to the karton service identity to avoid disrupting production services
• permanently setting the persistent attribute to False - the bind will disappear after the service quits
• not sending the (error) logs to karton listeners - this will help you to avoid spamming logging services in your deployment

The debug mode works as any other karton configuartion and can be set by:

• setting the env value KARTON_KARTON_DEBUG=1
• setting debug=1 in the karton section in karton.ini
• passing --debug to karton services via cli

Random suffix as well as -dev. It's nice to see immediately which services are the dev ones. But I see the code already does that.

setting the env value KARTON_KARTON_DEBUG=1

A bit uglier than just KARTON_DEBUG but I understand this is consistent with other config variables. So makes sense I guess.
