Bug description:
  When raft leadership changes, any leader-only connections will be
  disconnected and will need to reconnect to the new leader. When this
  happens, the IDL will return a txn status of TRY_AGAIN. The current
  code tries to do an exponential backoff with sleep() due to an issue
  where those can be spammed 1000s of times a second. This sleep also
  prevents reconnecting quickly because idl.run() is not called rapidly
  and can lead to timeouts.
