Retry mechanisms on tasks requiring internet connection.

[joaogbcravo]

Hey!

Ask: Can the tasks that require internet connection have the retry/delay/until block ?

Reasoning: In weak networks I'm hitting the problem that running the roles are not working on first try, but a second or third attempt make it work.

Ps: I'm happy to create the Pull Request if you accept this idea.

This sounds fine. I'll review any PR you put up. I would prefer a retry scheme (something like 5 times, with second delay?) See what works for your setup.
