Job Queue supervisor that can be started with client applications.

The EctoJob.Supervisor will start the required processes to listen for postgres job notifications, GenStage producer and ConsumerSupervisor to process the jobs.

Example:

def start(_type, _args) do
  import Supervisor.Spec

  children = [
    supervisor(MyApp.Repo, []),
    supervisor(MyApp.Endpoint, []),
    supervisor(EctoJob.Supervisor, [[
      name: MyAppJobQueue,
      app: :my_app,
      repo: MyApp.Repo,
      schema: MyApp.JobQueue,
      max_demand: 100]])
  ]

  opts = [strategy: :one_for_one, name: MyApp.Supervisor]
  Supervisor.start_link(children, opts)
end
