time_window always gets set to interval

[lynchc]

create a config with

{
    "interval": "1minute",
    "time_window": "10minute",
}

and view graph when it fails. You'll see that time_window is ignored and interval is always used instead.

actually it looks like this works but only when specified per alert. Setting it globally doesn't work. The docs are confusing for this as it lists time_window in main config section
