Mal Graty 693627a858 Emulate Boto when using role metadata
Use the behavior established in the botocore python library to inform
how and when instance metadata is fetched in an attempt to acquire valid
AWS credentials.

- Use it as a fallback when no other credentials are provided
- Set the timeout of metadata requests to 1 second

Mal Graty 48eaa0e5bf Let AWS DNS API code pull creds from instance role
Add option (AWS_USE_INSTANCE_ROLE) to have the AWS DNS API driver pull
the necessary credentials from the AWS EC2 instance metadata endpoint
when required.

This is a non-breaking change as it only takes effect when explicitly
turned on via the environment variable, and fails safe back to the
normal code path.
