feat: Update function name and add documentation for spawning clients

- Renamed the `spawnClients` function to `SpawnClients`
- Added documentation for the `SpawnClients` function, explaining its purpose and usage
- The `SpawnClients` function creates multiple clients connected to a given address using the `instrumented_resp_connection.NewFromAddr` function
- Clients are expected to be closed after use
