Feature Description

First, the sts token can be provided from any situation, and secondly, this makes it possible to cache the sts token.

Problem and Solution

Currently, we only support setting the security token from environment variables or loading it from the Aliyun STS service. However, our security token is provided by a service other than a standard STS service. This means that the intermediate service will request the STS token from the Aliyun STS service and return some aggregated response. This is why we cannot use the STS endpoint (and we cannot have an OIDC token file).
