[MH-11815] As a user I expect changes to be reflected in the Admin UI immediately - Opencast

Details

Severity:
Usability Issue
Steps to reproduce:

Hide
The Admin UI uses a 5 second polling interval to refresh table data. In a lot of places, the views will only be updated in those intervals.
This leads to a bad user experience: If a user deletes an element, for example, he will expect the table to reflect that change immediately after closing the confirmation dialog - not just after potentially 5 seconds.
