Closes #529

  • Add --transaction-drop-rate <0.0-1.0> flag: randomly drops transactions with the given probability, simulating
    packet loss or leader rejection
  • Add --transaction-execution-delay-ms <ms> flag: applies a random delay (0 to N ms) before executing each
    transaction, simulating out-of-order processing under high throughput
  • Add TransactionStatusEvent::Dropped variant returned to the RPC client when a transaction is dropped

Usage:

surfpool start --transaction-drop-rate 0.1 --transaction-execution-delay-ms 200
