Subject: Add case for handling infinity for idle/request_timeout

Currently cowboy assumes that idle_timeout or request_timeout is
a number and always starts timers. Similar situation takes place
in case of preface_timeout for http2. This commit adds case for
handling infinity as a timeout, allowing to not start mentioned
timers.
