Title: Kernel status/shutdown from dashboard

this is a partial fix for #1515 ,
It replace the `delete` button by `shutdown` button when kernel are running.
the list is updated when dashboard page get focus, and refresh every 60 seconds.
Refresh stop when page loose focus.

It also move the `clear_list` when clicking on the refresh button to avoid flickering.
