Start one or more Pulse.Discover workers to look up registered nodes for required services.

The module taks 3 parameters in a keyword list, for legibility:

• service - A binary indicating the service name to discover.
• poll - An integer indicating the number of seconds to wait between discovery refreshes.
• delay - An integer indicating the number of seconds to wait before first discovery.

children = [
  worker(Pulse.Discover, [[service: "my_service", poll: 5, delay: 1]])
]

Each Pulse.Discover worker is only responsible for one service, but you can discover multiple services by declaring more than one worker.

children = [
  worker(Pulse.Discover, [[service: "my_service", poll: 5, delay: 1]], id: MyApp.MyServiceDiscover),
  worker(Pulse.Discover, [[service: "my_other_service", poll: 5, delay: 1]], id: MyApp.MyOtherServiceDiscover)
  # ...
]

The configuration options should be tuned for your application, however the values shown above are a good baseline.
