1. Add `retry_strategy` interface and default implementation for exponential back-off retry strategy.
2. Add new S3 related errors, also introduce additional errors to describe pure http errors that has no additional information in the body.
3. Add retries to the s3 client, all retries are coordinated by an instance of `retry_strategy`. In a case of error also parse response body in attempt to retrieve additional and more focused error information as suggested by AWS. See https://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html. Introduce `aws_exception` to carry the original `aws_error`.
4. Discard whatever exception is thrown in `abort_upload` when aborting multipart upload since we don't care about cleanly aborting it since there are other means to clean up dangling parts, for example `rclone cleanup` or S3 bucket's Lifecycle Management Policy.
5. Add tests to cover retries, and retry exhaustion. Also add tests for jumbo upload.
6. Add the S3 proxy which is used to randomly inject retryable S3 errors to test the "retry" part of the S3 client. Switch the `s3_test` to use the S3 proxy. `s3_tests` set afloat `put_object` problem that was causing segmentation when retrying, fixed.
7. Extend the `s3_test` to use both `minio` and `proxy` configurations.
8. Add parameter to the proxy to seed the error injection randomization to make it replayable.
