Refactor Pipeline / Transaction to consume responses based on their requests, not rely on pipelinedCommands

* remove pipelinedCommands field at Connection class
** it was a risky state value
*** it was under 0 or over 0(though all commands are executed) while some situation
* remove Connection.getAll(), Connection.getAll(int except)
