docs: @overload credentialsFrom(data, credentials = null)
  Creates a credentials object from STS response data containing
  credentials information. Useful for quickly setting AWS credentials.
  
  @note This is a low-level utility function. If you want to load temporary
  credentials into your process for subsequent requests to AWS resources,
  you should use {AWS.TemporaryCredentials} instead.
  @param data [map] data retrieved from a call to {getFederatedToken},
  {getSessionToken}, {assumeRole}, or {assumeRoleWithWebIdentity}.
  @param credentials [AWS.Credentials] an optional credentials object to
  fill instead of creating a new object. Useful when modifying an
  existing credentials object from a refresh call.
  @return [AWS.TemporaryCredentials] the set of temporary credentials
  loaded from a raw STS operation response.
  @example Using credentialsFrom to load global AWS credentials
  var sts = new AWS.STS();
  sts.getSessionToken(function (err, data) {
  if (err) console.log("Error getting credentials");
  else {
  AWS.config.credentials = sts.credentialsFrom(data);
  }
  });
