Fixed some inconsistencies on provider dashboards.

- Red crosses were added as part of ManageIQ#4453 that caused them to show up on all aggregate status cards on all provider dashboards, fixed the condition and removed setting of redundant notification hash for providers when it is not needed.
- Show status icon under Alerts in aggregate card if Alerts are configured for a container provider, otherwise show "No data available" empty pf card.
- On Containers Overview dashboard, Fixed to not show provider icon in Provider status aggregate card, it should only show count of providers with a link to list view to Container Providers show list.
- Added a title on Container Overview dashboard screen, since that's the only screen on that subtab there are no breadcrumbs on the screen.
