add aggregator for parallel requests

Browse Source 
ParallelRequestsAggregator generates a line plot that shows the number
of parallel requests among the plotted events.
This plot has two issues:
1. It only considers events that are plotted. Events that occur later,
   but were started within the plotted time frame are not considered.
2. For performance reasons we are only plotting points when a value
   changed. This leads to diagonal lines.
