What this PR does / why we need it:
Revises the exponential backoff parameters such that the retries are not cancelled
after 20s.

These parameters are chosen so that the maximum retry time is 300s +/- 120s.

The wait method from API machinery continues to be employed, and is compared to the
Full Jitter and Decorrelated Jitter approach using the AWS concurrent client sample simulation below.

These parameters compare well to the Full Jitter method, which is one of the recommended approaches.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #1283
