fix(aws): improve credential handling and client lifecycle (#1719) - Version 0.x

[andormarkus]

This PR addresses issue #1719 by improving AWS credential handling and client lifecycle management across the AWS plugin.

Key changes:

• Store AWS credentials in instance instead of global env vars to prevent credential leakage
• Use async context managers for AWS clients to ensure proper resource cleanup
• Add proper credential validation to fail fast if credentials are invalid
• Fix session token handling for temporary credentials
• Ensure proper resource cleanup across all AWS services

The changes make the code more robust, safer, and consistent across all AWS services while properly handling async operations.

Hi @jayeshp19

We solved the credentials issue for version 1.x via #1849.
This PR is for version 0.x. Should I backport the code from 1.0 into 0.x ?
