Support AWS_EC2_METADATA_V1_DISABLED env variable

[stanhu]

This was added in the upstream AWS library: https://github.com/aws/aws-sdk-ruby/pull/2924

I think credential_fetcher would needed to be updated to avoid GET requests (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html) and only use PUT requests.

Thanks for the heads up. Definitely happy to support this work, but also definitely haven't been actively using EC2 in a very, very long time (so I don't feel confident/prepared to do the work myself).
