Add autoSubmit capability to IotProvider

I'm using IotProvider to take advantage of they ability to dynamically control which topologies are running.

There are times when I want some or all registered topologies to be submitted when I start the application - not requiring device "submit" command to start them. This seems like it could be a common usage model.

Since IotProvider already provides a convenience wrapper over ApplicationService.registerTopology(), I'd like IotProvider to also provide a convenient way to submit a registered application and/or be able to specify that a registered application will be automatically submitted when I start the IotProvider.
