Retry our API calls for a little more resiliency

Only part I am unsure of is the try/catch line: except AssertionError:

It seems that perhaps that will only catch assert lines. But what if requests library call throws its own exception, ie: except (requests.exceptions.RequestException, requests.urllib3.exceptions.HTTPError):

If there was a connection error..

Also would you be open to a PR that allows the number of retries to be configurable via command line arg?

[thomasrockhu]

@nmoinvaz I'll add a PR for the first issue, feel free to open one for the second
