Amazon Authentication

The EC2 Tagger Processor uses a credential chain for Authentication with the EC2 API endpoint. In the following order the plugin will attempt to authenticate.

1. STS Credentials if Role ARN is specified
2. Explicit credentials from 'access_key' and 'secret_key'
3. Shared profile from 'profile' (https://stackoverflow.com/a/66121705)

The next will be the default credential chain from AWS SDK Go

4. Environment Variables
5. Share Credentials Files with default profile
6. ECS Task IAM Role
7. EC2 Instance Profile

The IAM User or Role making the calls must have permissions to call the EC2 DescribeTags API.
