Reduce max_attempts default value

[shhlife]

• I have read and agree to the contributing guidelines.

Currently max_attempts is set to 10, which can make it appear that the framework is hung when it's really just trying something a number of times.

Would like to discuss reducing the default number to 2 or 3. Usually if something is going to fail, one or two retries is fine - and if the user needs more they can always increase it.

I wonder if we should retry at all? Should it be opt-in?

[shhlife]

good point, maybe not? Usually things fail due to something that retrying wouldn't resolve.. like an invalid api key.

Or maybe we just need to refine the ignored exception types.

yeah, that would help :)
