[Bug] Profile aren't properly handled, return wrong credentials

[Vadorequest]

I won't make a PR because those existing seem dead and don't want to waste my time, but know that the profile isn't correctly managed as it is now.

Current version (buggy):

if (program.profile) {
  var newCreds = AWS.config.credentials;
  newCreds.profile = program.profile;
  AWS.config.update({ credentials: newCreds });
}

This doesn't work as expected, it doesn't select the credentials for the right profile but from the first defined profile. It may have worked with a very simple setup (1 profile) but doesn't really handle multi profiles.

---

Fixed version:

if (program.profile) {
  var newCreds = new AWS.SharedIniFileCredentials({ profile: program.profile });
  newCreds.profile = program.profile;
  AWS.config.update({ credentials: newCreds });
}
