A callback is called by the Tx_queue at various stages of a submitted transaction's life.

The next tick after its insertion in the queue, a transaction is submitted to the relay node within a batch of eth_sendRawTransaction requests.

Depending on the result of the RPC, its callback is called with either `Accepted or `Refused).
As soon as the transaction appears in a blueprint, its callback is called with `Confirmed. If this does not happen before 2s, the callback is called with `Dropped.
