[CORE] Add feature to make video refresh requests pending for being process 

When there are multiple video refresh request sent within defined VIDEO_REFRESH_FREQ, only first one is being processed. The rests are discarded.

With this feature, any second video refresh request is marked as pending and is being processed as soon as possible, so within the interval given by VIDEO_REFRESH_FREQ.
