do tx sending in subprocess #250

Closed wphan closed 1 month ago

wphan commented 1 month ago

Add a base class TxThreaded that Bots can extend to get tx sending and land rate tracking in a separate process. The spawned process handles signing and sending transactions via generally recommended practices, retrying on a 1s interval, and listening to logSubscribe for transactions mentioning pubkeys registered via TxThreaded.sendSignerToTxThread

If metrics are enabled, the following metrics are added via TxThreaded:

# HELP tx_sender_metrics TxSender thread metrics
# TYPE tx_sender_metrics gauge
