Dashboard does not refresh when state changes

[David Kranz]

If you terminate a VM from the dashboard it does not disappear from the UI until you refresh the browser window or go to another page and return. Likewise for the display of the current state of a VM that has been launched. I think the UI needs to poll the state periodically for changes to what is being displayed.

Commented on https://bugs.launchpad.net/horizon/+bug/884461 which is related to this. Essentially the new data table component needs to provide the ability to define field values which indicate a visible row is in a transitioning state and therefor needs to be polled for updates. Something like:

class InstancesTable(tables.DataTable):
    status = tables.Column("status", poll_values=("build", "terminating))

Gabriel will have better feedback on the implementation but that's the general idea.

I'm in favor of extending datatables to handle this... I think extending the existing status_choices API on tables.Column, or at least building from that as a starting point, is a wise course of action.

Fixed with AJAX table querying merge.
