feat: add CLIENT PAUSE and CLIENT REPLY subcommands

[furkan-bilgin]

This PR is a part of #2422

I have added two subcommands for the command CLIENT:

• CLIENT PAUSE: Pauses processing of either WRITE or ALL commands until after timeout milliseconds.
• CLIENT REPLY: Stops server from sending replies to the client, starting; immediately if OFF, or skips one if SKIP. Starts sending replies if ON.

@furkan-bilgin Looks good if you can add some Go test cases to cover this. And another point is that we should disable the EV_READ for connection while pausing?
