Documentation for supported retry mechanics

[kir-titievsky]

There does not seem to be any documentation for what retry mechanisms are implemented by the clients. Would be wonderful if this were highlighted, explicitly. These cases are important in particular for users to decide whether to implement their own error handling:

1. Re-tryable errors.
2. Non-retryable errors.
3. Prolonged non-retry-able errors (hours).

@kir-titievsky Currently there are no retry mechanics and we have started this discussion. Closing this in favor of the discussion in #2694

Danny, I think that in itself would be very might be useful to highlight at the top level of the README.

The top level of the README is pretty extreme, but I'm happy to put it somewhere "near the top"

Thank you!
