### Summary

The way in which we are using `retry_with_delays_and_condition` along with `generate_jittered_backoff` may prevent subsequent failures from retrying if the generator was consumed by previous calls to `_call_galaxy`.

It appears as though the `backoff_iterator` in this case is global for all calls, and not refreshed per call to `_call_galaxy`:

https://github.com/ansible/ansible/blob/c564c6e21e4538b475df2ae4b3f66b73decff160/lib/ansible/galaxy/api.py#L328-L332

Currently every call to `_call_galaxy` consumes at least 1 item in the `backoff_iterator`, even when a retry isn't attempted, so after 6 calls, no-retries would ever be performed.

This may require making `backoff_iterator` take a callable, or something that can regenerate the iterator, instead of acting as a global state iterator.
