* Initial implemntation of returning 529 for rate limits - bump aws iam and sts packages to v1.14.31 to get mocking interface - promote the iam and sts clients to the aws backend struct, for mocking in tests - this also promotes some functions to methods on the Backend struct, so that we can use the injected client Generating creds requires reading config/root for credentials to contact IAM. Here we make pathConfigRoot a method on aws/backend so we can clear the clients on successful update of config/root path. Adds a mutex to safely clear the clients * refactor locking and unlocking into methods on *backend * refactor/simply the locking * check client after grabbing lock
