 *                          Default: ""
 * @param function          Lambda function name to call
 *                          Example: "helloWord"
 * @param qualifier         Optional - Lambda function version or alias
 *                          Example: ":1"
 *                          Default: "$LATEST"
 * @param payload           Optional - Lambda function payload in JSON format
 *                          Example: "{"key1":"value1", "key1":"value2"}"
 *                          Default: null
 * @return                  A map with strings as keys and strings as values that contains: outcome of the action, returnCode of the
 *                          operation, or failure message and the exception if there is one
