Minio 8.0.5 introduces problematic changes

[alxndrsn]

minio v8.0.5 introduced request retries:

• https://github.com/minio/minio-js/releases/tag/8.0.5
• add retry for http retryable requests minio/minio-js#1390

These are hardcoded to retry failing requests 10 times, with ~1.5 second exponential backoff:

• https://github.com/minio/minio-js/pull/1390/files#diff-400afaf715c102aff7ab2cb86d9c5a79de95a6431c6947f19c7d823bcb6ec5c7R31-R33
• https://github.com/minio/minio-js/pull/1390/files#diff-400afaf715c102aff7ab2cb86d9c5a79de95a6431c6947f19c7d823bcb6ec5c7R55-R59

This means that a bad S3 server could cause an individual S3 upload/get/delete request to delay for > 15 minutes.

This is especially problematic as minio S3 requests can occur inside postgres transactions.

There is also a report of out of memory issues with this minio release:

• OOM in the 8.0.5 when uploading large files minio/minio-js#1406

Suggested resolution

1. downgrade to minio v8.0.4
2. consider whether postgres transactions should ever be spanning external HTTP requests. Note that this may also be the case for pyxform and other external service requests

These issues have not been fixed in minio v8.0.6 (see #1437).
