support reading AWS_ keys from environment variables

[alistair]

The aws node sdk supports configuration via environment variables [1].

Sadly I think that by the way you default values to "" with your call to AWS.Lambda means that the sdk does not attempt to look at these environment variables and instead you get a credentials error.

I did not try environment variables, but I have my AWS credentials in ~/.aws/credentials, and am able to use this library to deploy just fine. So I'm not sure whether the "" default is causing any problems. I'm using aws-sdk@2.3.14.

Hi, I tried the following command, where reads access from the env, and it worked.

AWS_ACCESS_KEY_ID= AWS_SECRET_ACCESS_KEY= gulp deploy

"node-aws-lambda": "^0.1.8"

Sounds like this can be closed!
