Update s3 credentials the backend on the go

[edogrigqv2]

🚨🚨 Feature Request

On the backend, s3 credentials expire very fast in 1 day.
We have to

• Be able to update credentials when the program starts, otherwise, users have to hub login again.
• For long uploads update credentials on the go. This is a much harder task, probably should be separated into a separate issue.

Description of the possible solution

Just run get_credentials logic when the hub module is loaded.

Hi @edogrigqv2 . I have a doubt. When you say S3 credentials are you referring to the normal Access Keys (IAM) or the credential used when creating Presigned URL?
