Log address of clients in scheduler log

[crusaderky]

When a client is started from inside a task, it would be very useful to know which worker it's from.
Please add the remote address (so that it can be matched with the worker's IP) to these log lines:

distributed.scheduler - INFO - Receive client connection: Client-worker-9eadd272-1c16-11ee-801f-16762cd4e735
distributed.scheduler - INFO - Remove client Client-worker-9eadd272-1c16-11ee-801f-16762cd4e735
distributed.scheduler - INFO - Close client connection: Client-worker-9eadd272-1c16-11ee-801f-16762cd4e735
