This was discussed couple times before and the reason this was never added is because of potential misuse of this by setting extremely high value, making the bubble virtually sticked to your screen forever. This should be handled by the server that should do the right thing(tm) like eg. Plasma does a word count and then with simple heuristic determines the display time. Regardless of Plasma however, the server should always have a sensible default that all apps should follow, therefore this option was never added and I still think it shouldn't be there today; I can't see a reason why would you want the bubble to be displayed for either very short time or very long time. For anything in between the server default should be good enough.
