There are several concepts that implements or requires periodical refresh after action in UPS Admin:

• Activity Log
• Metrics
• Variants
• Application List
• App Creation Wizard

I suggest we manage them under one RefreshService service so that they share implementation.

We shouild also leverage kind of exponential backoff when managing timeout/interval (e.g. start on 300ms updates, but continue with prolounging the timeout up to several seconds, e.g. 5s or 10s (depends on the action we perform)).

The service should:

• de-duplicate the requests for updates (so that one screen does not poll several times the same source, e.g. because several messages were pushed)
• allow to provide condition determining when the interval should stop polling
• destroy periodic/scheduled action at navigation ($scope.$on("$destroy", ...))
