error: "credential should be scoped to correct service"

[dtenenba]

After setting environment variables:

export AWS_ACCESS_KEY_ID=XXX
export AWS_SECRET_ACCESS_KEY=YYY
export AWS_REGION=us-west-2
export AWS_DEFAULT_REGION=us-west-2

and running the proxy:

aws-signing-proxy -target https://batch.us-west-2.amazonaws.com -port 8081

I hit it in another window and get the following error:

$ curl -X POST http://localhost:8081/v1/describecomputeenvironments
{"message":"Credential should be scoped to correct service: 'batch'. "}

I don't think credentials are the problem because in the first window, after setting environment variables, I can call the API directly:

$ aws batch describe-compute-environment
... successful output omitted ...

This is likely because the current version hardcodes "es" as the service when doing the signing. I just merged #20. Please try again with master passing -service batch to see if this resolves the issue. Thanks!
