Possibility to turn off retries

[zuiderkwast]

Turning off retries (not counting redirects) allows a project to have their own failure and retry handling, such as:

1. Logging errors in custom ways
2. Having custom back-off timer logic
3. Tweaking the number of retries depending on the type of the error

Possible ways to turn off retries:

• Add an optional number-of-retries parameter to each function
• Add a number-of-retries option as an application configuration parameter ⭐

As indicated, I'm leaning towards the 2nd option, since it doesn't clutter the API as much as the 1st option, but there might be other aspects that I haven't thought of.
