CCA: Ensure the duration of capture metrics is integer

The value of a GA event is not allowed to be a floating number and the
event will be unexpectedly dropped causing the incorrectresults of
video capture metrics.
See: https://support.google.com/analytics/answer/1033068

This CL ensures that eventValue is an integer if presents in GA event,
and also returns integer when querying the duration from RecordTime.
