Method WebDriver->setCookie() has an argument to suppress debugCookies().

Methods seeCookie(), dontSeeCookie(), resetCookie() and loadSessionSnapshot() don't provide this.

We're using a helper to set cookies for quick access of our login restricted things and the cookie output is kinda noisy, which we'd like to suppress.

I could come up with a quite simple PR to add this. Do you think this would find general acceptance?
