This is to provide a clean path to future extension work such as adding
a _use_container_role function to offer similar support for ECS
containers.
The $_using_role flag has also been made generic so that future role
providers can also make use of it.
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
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.

message:
SC2034: $VARNAME appears unused. Verify it or export it.
most of these are related to the style:
we generate global vars, which are used in other functions.
the var "lexical_url" was really unused (left it as comment)
the travis-check now does not need anymore special flags.

Ignoring the Chthlulu argument 😃, Route53 returns its XML all on one line, making not possible to grep the hosted zone record with egrep/sed.
This change splits the XML in multiple lines, so that parsing can succeed.
