public String execute(String command) throws Exception {
    executeCommand(command);
    return gfsh.outputString;
  }
@param command the String command to execute
@return Command result object

@deprecated use executeAndAssertThat(command). if you really need to get the result object
            to do assertion, you can use hasTable().getActual() or hasData().getActual
            after that method call.
