Adds debug and warn logging around AWS credential chain generation,
specifically to help users debugging auto-unseal problems on AWS, by
logging which role is being used in the case of a webidentity token.
Adds a deferred call to flush the log output as well, to ensure logs
are output in the event of an initialization failure.
The result will still pass gofmtcheck and won't trigger additional
changes if someone isn't using goimports, but it will avoid the
piecemeal imports changes we've been seeing.

If the Content-Length header wasn't being sent back, the current
behavior could panic. It's unclear when it will not be sent; it appears
to be CORS dependent. But this works around it by not trying to
preallocate a buffer of a specific size and instead just read until EOF.
In addition I noticed that Close wasn't being called.
https://docs.aws.amazon.com/sdk-for-go/api/service/s3/#GetObjectOutput
specifies that Body is an io.ReadCloser so I added a call to Close.
Fixes#4222
* Add some extra efficiency
