0.4.x - fix(config): check if AWS key and secret are not empty

[pflorek]

if using AWS_ACCESS_KEY_ID='' or AWS_SECRET_ACCESS_KEY='' an exception will be thrown

Error executing "PutEvents" on "https://events.us-east-1.amazonaws.com"; AWS HTTP error: Client error: `POST https://events.us-east-1.amazonaws.com` resulted in a `400 Bad Request` response:
{"__type":"UnrecognizedClientException","message":"The security token included in the request is invalid."}

note : it's only required if you provide them, if you are in an aws instance (ec2, ecs, kubernetes, ...) it will be provided not by the configuration, but by the instance

Yes, I prefer to use the instance profile, task role or service account instead of access keys and let the credential chain resolve it.

Just got from the infrastructure an empty string instead a null and then got that error. Would be really nice to have a not empty check instead a not null.
