Automatic auth discovery inside AWS

This would be great. Easy win would be using the Java lib but only the auth module or something. However, I think it should be fairly easy to stay purely Scala without using AWS SDK. I might be able to work on this feature this weekend, will post a branch here for visibility.

I have opened a draft PR. I need to write more tests but I think the current logic should work, however, there is a piece of logic that I'm still not happy with but can't think of a better way to do it atm: https://github.com/d2a4u/sqs4s/pull/128/files#r453246432

@BalmungSan I have released 1.1.0. Cheers

From the AWS doc that you sent, this command gets the cred but requires a role (s3access in their example). However, in the AWS SDK source code, looks like what they do is just getting the 1st one from a list of creds without specifying any role. I find this a bit weird because from their code, it is potentially a security risk since it might not getting one for the right role, what do you think?

[BalmungSan]

For what I understand @d2a4u in the link I passed one requires to know beforehand the role name, this is impractical.
Also, AFAIK, you can only assign one role to each service / image / container / etc, so probably they know that the list can be either empty or be a single element list, so that is why they just access the first position (+100 points to Option 😆).
