Poll on the list landing page to update new lists

The main list page should periodically poll for updated list information. When you've already loaded the page, and someone else takes an action on a list (refresh, create new, edit), those updates should appear on the list landing page.

Refresh:

Scenario: List landing page displays updated list info
Given user A has the list overview page open
    And user B initiates a refresh on List 1
When the refresh on List 1 completes
Then user A sees updated info displayed for List 1
    List name, record count, last updated date
 

New list:    
Scenario: List landing page displays newly created list
Given user A has the list overview page open
When user B creates a shared list, List 2
Then user A sees a notification "List 2 was created. Reload to see changes. Note: the list may not appear based on filters." "List 2 was created. Refresh to see changes. Note that list may not appear if filters are applied." 
    And List 2 appears on the list overview page 
    And number of lists is updated to reflect the new list
    
Scenario: List landing page: multiple lists are created within polling period
Given user A has the list overview page open
When user B creates shared lists, List 2 and List 3
Then user A sees a notification "New lists were created. Reload to see changes. Note: new lists may not appear based on filters." "New lists were created. Refresh to see changes. Note that list may not appear if filters are applied."
    And List 2 and List 3 appear on the list overview page 
    And number of lists is updated to reflect the new list
