Add parameter to not log Response during executing REST requests

REST requests (ex. `sendPOST`) always output response , through `execute` method: `$this->debugSection("Response", $printedResponse);`

However our tests do a lot of requests, and in return get whole body of web page, which pollutes log.

This is why I would like to add parameter, which suppresses printing whole response. If such contribution would be welcomed, I can provide pull request.

首先閱讀 issue 中提到的 execute 方法和 sendPOST 請求路徑，重點關注如何到達 Response debugSection 呼叫。追蹤請求參數如何透過 REST 方法傳遞。完成的標準是，呼叫端可以抑制完整的 Response 輸出，同時請求繼續正常執行。
