[Stack Monitoring] SetupMode pane renders stale data

[klacabane]

When entering the setup mode in kibana instances page, the app should poll a setup-related api /api/monitoring/v1/setup/collection/cluster/:id every n seconds to update instances migration state, as well as notifying the user that data was detected and migration is done if the pane is open.

In the react code we only call that api once when entering the setup mode and then continuously renders stale data. The issue may appear in any pages that use the setup mode.

Relevant code that is maybe not called on re-renders ?

We need to call the method that you mention inside the refresh callback when the setup mode is enabled as it was done in Angular here
