      INDY 17.24: Node Perf, INDY 17.25


      Build Info:
      indy-node 1.2.49

      Steps to Reproduce:
      1. Install pool of 4 nodes.
      2. Place load test files to /home/indy at any node (e.g. Node 1).
      3. Run `python3 add_keys.py Steward1 000000000000000000000000Steward1`.
      4. Run `python3 load_test.py -c 10 -r 1000` as indy user (works).
      5. Run `python3 load_test.py -c 20 -r 2000` as indy user (doesn't work).

      Actual Results:
      It's unable to run Step 4 because script can't connect to node where we run load scripts (raise Exception("Not connected fully"). Restarting of this node doesn't help. There is a message in node log about "found node state empty .. try to recreate ledger".

      `read_ledger --type=domain --count` returns the next:
