# Override the AWS retry settings with Lono AWS clients.
#
# The aws-sdk-core has exponential backup with this formula:
#
# 2 ** c.retries * c.config.retry_base_delay
#
# Source:
# https://github.com/aws/aws-sdk-ruby/blob/version-3/gems/aws-sdk-core/lib/aws-sdk-core/plugins/retry_errors.rb
#
# So the max delay will be 2 ** 7 * 0.6 = 76.8s
#
# Only scoping this to deploy because dont want to affect people's application that use the aws sdk.
#
# There is also additional rate backoff logic elsewhere, since this is only scoped to deploys.
