Index submitted transactions for nonce tracking in tx client

[ninabarbakadze]

Description

Currently, if a transaction has a nonce mismatch, we query the transaction nonce and resubmit transactions with the updated nonce. We should stop resubmitting transactions on users' behalf and instead track all submitted transactions and their nonces locally. If a transaction gets evicted during ConfirmTx(), we can readjust the nonce to what it was before the transaction was submitted on-chain, allowing users to resubmit transactions if they choose to do so.
