Allow specific queues to be started independently

[spencerdcarlson]

• Fix for issue 67

Added a manual_queue_supervisor.ex which is a clone of supervisor.ex except it takes an options keyword list as the first parameter.

Modified TaskBunny.Supervisor.start_link to take options

The options are eventually passed down to the TaskBunny.WorkerSupervisor where it checks for a list of queue names, or a namespace to start.

Consumers of the task_bunny library can disable runtime dependency which will disable the automatic start of the TaskBunny Application and then call the TaskBunny.ManualQueues TaskBunny.Supervisor manually from their umbrella application

children = [
  supervisor(
        TaskBunny.Supervisor,
        [
          TaskBunny.Supervisor,
          TaskBunny.WorkerSupervisor,
          :publisher,
          [queues: [namespace: "my-name-space"]]
        ]
      )
]
Supervisor.start_link(children, [strategy: :one_for_one, name: MyApp.Supervisor])

# disable runtime dependency to disable auto start
defp deps do
[
  {:task_bunny, "~> 0.3.2", runtime: false}
]
end

We should also update the readme with the new configuration options.

I will definitely use this! Can't wait for it to drop.
