Problem
We wish to test how long the cluster takes to recover after a partition.
Summary of Changes
Sets up a buildkite test that partitions the network for a specified time. Then by measuring validator confirmation times, we can measure the time needed for the cluster to recover.
Here's an example run of 5 nodes with 2 partitions that warmed up for 120 seconds, partitioned for 300 seconds and then took 42 seconds to recover after resolving the partition.
