UI: Add description field in the events for objects

[rajujith]

The required feature described as a wish

As a User/Admin/Operator I would like to see the description of the events as well in the events tab per objects like instance, host, etc. This field is available in the events tab in general but not available per object by default. We can select the description field but this selection is not persisted. When I click on something else and come back this view is gone to the default selection.
