Delay 5 minutes in DimensionalTimeSliceCrawler for partition creation of live event

[wjyao0316]

Description

This commit add 5 minutes delay to partition creation on live event in DimensionalTimeSliceCrawler.

In general, newly generated events become queryable after 30 ~ 120 second. Delay 5 minutes give enough time for the newly generated events to become queryable to largely reduce the possibility of losing events due to eventual consistency in vender API side.
