generating Credentials from 2 ByteStrings

[joeyh]

My program already stores AWS credentials in its own way, so I need a way to get from ByteString -> ByteString -> Credentials

It's certainly possible to write that in my program, but then I have to worry about the v4SigningKeys and iamToken fields, which seem like implementation details that could change. And one of them, being an IORef, I'm wary of constructing on my own, since making an IORef that's empty when it should be full can lead to problems, for example.

So, I suggest providing in aws:

genCredentials :: ByteString -> ByteString -> IO Credentials

Using that might also simplify the implementation of loadCredentials*

This would also make it easier to read creds from custom config files, which is commonplace, say if you're working with a snap web app.

You're lucky that I didn't tell you to make a pull request and just went ahead and implemented it. :P
