The addition of `exclude_specified_queues` allowed all specified queues to be treated as exclusions, implying that all jobs in those queues not be handled by the workers. However, this only allows application of this behaviour globally. What we want is the ability to create two or more pools, where some pools handle jobs from the given queues and other pools handle jobs that are not from the given queues.

To implement this, we check if the `exclude_specified_queues` is not set and treat this as a request for automatic detection of exclusions. By adding a "!" to the beginning of a queue list, only the workers that handle that list of queues will behaves as if the `exclude_specified_queues` flag had been set.
