Tasks that need an Internet connection should wait until we have an Internet connection before executing

We can implement this via a needsInternet property on SYNQueueTask.

Then we can inject a dependency for the task that waits for reachability to return with a valid connected status before completing.

This can help us do things like web requests that are queued then assured to be completed the next time we have Internet, rather than just errororing out after retries run out.

The queue should not have any concept of what the Internet is. It's a common use case, but we need a more generic solution.

It could just be a generic "DependancyBlockProtocol" with a simple method that returns a bool based on if a condition is met or not. Then depending on the return value, on true it would go ahead and execute the actual task and on false it would postpone it and try to call this block of code again in idk x seconds?

This would be a "pull" model. Could be adapted to make it work with events/callbacks instead. Idk, just an idea. I definitely can see myself using this lib but with an internet connection dependancy.

@jyounus Thanks for the feedback! I like that idea, but like you said it needs to be based on a callback because we don't want to keep polling for it (would a false returned from it be considered a failure?).

I completely agree that an internet connection dependency is necessary and it's a top priority.
