Statistics (aggregate per day (run/lift) - Total time on the chairlifts

[beingtranquil]

Describe briefly your feature.
Total time on chairlifts determines the time total time for the during which the person happened to be on the chairlift.

Describe the solution you'd like
We have a dependency on Group #4-6 - Statistics (service functions, Ski statistics) where they will find the "Total travel time on the chair lift" and this function can be used to provide a UI element for displaying this statistic.

Describe alternatives you've considered
As an alternative, if the aforementioned function doesn't work well, we can use "Identify the segment when a user is on the chairlift" and add all the segments in the day to find out the total time on chairlifts.

Added a text field to the ChairLift ui. The data was not bind with the text field. So, it was partially implemented.
