      We'd like to introduce a concurrency/FSM workload that triggers config server failovers to verify that they occur transparently to clients.

      Basic implementation notes:

      • Add a new workload to jstests/concurrency/fsm_workloads/ that randomly steps down / freezes / etc. the config server primary
        • Note: You may want to prevent the workload from running with itself
      • Modify jstests/concurrency/fsm_libs/runner.js to support "persistent" workloads that run in each schedule

      Here's what a schedule looks like now:

      [ [ "jstests/concurrency/fsm_workloads/update_array_noindex.js" ], [ "jstests/concurrency/fsm_workloads/update_multifield_isolated_multiupdate_noindex.js" ], [ "jstests/concurrency/fsm_workloads/update_rename_noindex.js" ]...

      Here's what the schedule should look like after:

      [ [ "jstests/concurrency/fsm_workloads/update_array_noindex.js", "jstests/concurrency/fsm_workloads/config_server_failover.js" ], [ "jstests/concurrency/fsm_workloads/update_multifield_isolated_multiupdate_noindex.js", "jstests/concurrency/fsm_workloads/config_server_failover.js" ], [ "jstests/concurrency/fsm_workloads/update_rename_noindex.js", "jstests/concurrency/fsm_workloads/config_server_failover.js" ]...
