Subject: [PATCH] threadgroup: don't log GreenletExit

This exception is always raised when a green thread is stopped. This
exception does not indicate any problem in a service, so it should not
be logged not to scare operators and developers that waste their time
debugging those exceptions in their deployment and unit test logs.
