What is the feature?

This is a part of a bigger feature ticket

Re-sending txns with higher gas price

This scenario occurs when the blockchain network is congested. In this scenario, a user who sent a transaction with a gas price of say, 5 gwei, would have to wait for long time before their transaction is mined (if the average gas price during that time is say, 20 gwei). In such cases, some users may prefer and afford re-sending the same transaction with a higher gas price of say, 30 gwei, to force their transaction through.

In order to resend a transaction with updated gas price, this new transaction must have the same nonce as the older one. By modifying just the gas price of the transaction object, the new transaction can be signed again and sent to the Ethereum node. Both those transactions would now have the same nonce, but the latest one with a higher gas price. Whenever one of them is mined, the other is automatically dropped.

How can it be done?

Please review their action plans below:

1) lacexd has applied to start work (Funders only: approve worker | reject worker).

i'd like to implement the fature, i the git repo and everything seems clear so far.
2) arbreton has applied to start work (Funders only: approve worker | reject worker).

Straight forward instructions, shouldn't be a problem to implement
3) bshevchenko has been approved to start work.

I'm approved by you to work on https://gitcoin.co/issue/DigixGlobal/dao-server/70/3349 so I think it makes sense to fix this issue for me as well
