1. Improve matching simulator isolation group metrics …

   Record isolation group information for additional events and use it to calculate the median, mean, and max latency of events per task list and isolation group. Additionally record the percent of tasks that are dispatched to a poller with that same isolation group per task list and isolation group. With the current implementation no scenarios leak tasks to another isolation group.
   
   Additionally provide a definition of getAllIsolationGroups so that the matching simulator doesn't deadlock due to panics in task list manager initialization.
   
   Create 6 new scenarios for zonal isolation. The first three (few_pollers, many_pollers, and single_partition) test a scenario where the total task throughput is easily manageable with any number of pollers but the number of pollers/partitions significantly impacts the performance. The next two (zonal_isolation, zonal_isolation_skew) show a higher throughput scenario which should still be manageable by the specified pollers for each isolation group. The latter of the two has the tasks skewed to the maximum that pollers from a single group should be able to process (64/12/12/12) vs (25/25/25/25).
   
   The final scenario, zonal_isolation_skew_extreme, has the tasks heavily skewed (90/3/3/3) beyond what a single group can handle.
