c.logger.Error(fmt.Sprintf(`failed to open a new channel for "%s"`, c.channelDescription), err)

We are seeing logs like [failed to open a new channel for \"live-profile-matching-with-matches-for-notification-assembler-go-retry-10000ms-later\" Exception (504) Reason: \"channel/connection is not open\"]",

The code in the link will ultimately return a chan amqp.Channel that will never get any items in it. This will result in the service being unable to pub/sub

Also, the abstractions around this area feel a bit complicated, we should try and simplify this
