CC-3131: Latency of stream authentication warning in Stream Settings page

- it compares boot time of liquidsoap and the time user clicks on "Save"
on stream setting page. The status only gets updated if the
"boot_time" > "user update time"
- as soon as a user click on save, status is set to "wating"
- since there is no timing issue, quering interval is reduced to 1 sec
