Transaction Submission Payments Load Testing Script

Load Test Flow:

1. Create N number of Transactions in the database for TSS to process
2. Poll database until all Transactions have completed
3. Query Horizon for each transaction and use those details to calculate and print metrics for the load test

CLI Flags:

    --databaseUrl            Postgres DB URL
    --horizonUrl             Horizon URL (default "https://horizon-testnet.stellar.org")
    --assetCode              Asset code (default "USDC")
    --assetIssuer            Asset issuer (default "GDQOE23CFSUMSVQK4Y5JHPPYK73VYCNHZHA7ENKCV37P6SUEO6XQBKPP")
    --paymentDestination     Destination address to send the payments to
    --paymentCount           Number of payment Transactions to create

CLI Usage Example:

% go run internal/transactionsubmission/scripts/tss_payments_loadtest.go \
--databaseUrl "postgres://postgres:password@localhost:5432/tss-testing?sslmode=disable" \
--horizonUrl "https://horizon.stellar.org" \
