/**
* AWS credentials provider chain that looks for credentials in this order:
*
* - Environment Variables -
*
AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
* (RECOMMENDED since they are recognized by all the AWS SDKs and CLI except for .NET),
* or AWS_ACCESS_KEY and AWS_SECRET_KEY (only recognized by Java SDK)
*
* - Java System Properties - aws.accessKeyId and aws.secretKey
* - Web Identity Token credentials from the environment or container
* - Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
* - Credentials delivered through the Amazon EC2 container service if AWS_CONTAINER_CREDENTIALS_RELATIVE_URI" environment variable is set
* and security manager has permission to access the variable,
* - Instance profile credentials delivered through the Amazon EC2 metadata service
