SDK Bugs

• aws/session: Fix SDK AWS_PROFILE and static environment credential behavior ()
  • Fixes the SDK's behavior when determining the source of credentials to load. Previously the SDK would ignore the AWS_PROFILE environment, if static environment credentials were also specified.
  • If both AWS_PROFILE and static environment credentials are defined, the SDK will load any credentials from the shared config/credentials file for the AWS_PROFILE first. Only if there are no credentials defined in the shared config/credentials file will the SDK use the static environment credentials instead.
