Description

Adding an action resend mechanism to prevent a transaction from being stuck due to unsuccessful broadcasting.

  • attempt to resend exact pending transactions if still unconfirmed after 1min from last send
  • allow a maximum of 3 attempts per transaction

Pre PR: #4497

Need further discussion:
How to avoid or alleviate network congestion when dealing with a large number of transactions? Feel free to show your mind
