Mention Discord username of the faucet requester in the response output of the bot

[CalinHumans]

Hi Vali,

Could you please have the faucet mention and tag the Discord:

Current output example at $request:
{
"transaction": "238626FAA44DCFE5D3E2B6862A1E23B13EB35AB0873B28ABFEA94AACB8AB6C0A",
"block": 48189,
"gas": 91313
}

And modified should be something like this:

@Discord_username
{
"transaction": "238626FAA44DCFE5D3E2B6862A1E23B13EB35AB0873B28ABFEA94AACB8AB6C0A",
"block": 48189,
"gas": 91313
}

Also, throttle message should look like:

@discord_username, you can request your uheart every 0.02 hours, please try again in 0.02 hours!

This is useful due to the fact that at some point, multiple users may request tokens in a short amount of time and there would be confusion in regards to which user does the transaction belong to

FYI, I am getting the following:

{
  "requester": "@undefined",
  "transaction": "02F61F34B117F59E06D5F39CF407116E559237A71642CF88D65AD3C93028CDE5",
  "block": 636002,
  "gas": 71897
}

Not it is returning @undefined instead of the actual requested. I am not sure if this is an issue on my end or not.

You should retry with the latest docker image, this was just fixed, and check the environment variables of gas and amount for the fee.

Hi yes, I created a script to delete all containers and images on start up of the faucet and now I see it is working perfectly for both fixes. Greatly appreciated.
