W. Trevor King 17171f7802 scripts/maintenance: Support ~/.aws configs for region ...

So folks don't need to bother setting --aws-region or $AWS_REGION to
use their usual default.  Docs for the config file settings are in
[1].

I've also adjusted the logic so that the precedence is:

1. --aws-region, falling back to
2. $AWS_REGION, falling back to
3. ~/.aws

Previously, $AWS_REGION took precedence, and has since the scripts
landed in 82bdd9fe (installer/scripts: AWS tag and delete scripts,
2017-06-28, coreos/tectonic-installer#1239).  But having environment
variables override explicitly-set command line options is not
idiomatic.
