large file messages from database need clarified

[baeolophus]

from workshop2 user with own data (Realistic size dataset): "3mb file (~100k visits) caused message “Processing is taking longer than expected. Please check back in a few minutes.”, then I quit out, logged out, and closed browser tabs. "

@tdpearson I think you said you already fixed this during the workshop, is that correct?

I have not made any changes to the notification. The alert notification should be replaced with a modal providing more feedback and options to the user. The polling retry count can also be adjusted.

A taskhistory and taskstatus page were created but not yet been added to the navigation bar or linked in the notification.
