Cancellation notifications are really core to writing good
cluster-aware clients, so I'm hopeful we can get it into Pika. I was
going through the docs on capabilities presentation, was little
unclear what format the table needs to be in. The spec seems to expect
a string there so I assume the table is encoded either in something
like Erlang or JSON. Going from the docs, would this be the right
capabilities string to pass to enable cancellation notification?

'{"consumer_cancel_notify" = true}'

Thank you again very much!
