Feature Request

Add retry mechanism for HTTP Provider.

Use Cases

Proxy agent can be flaky, I'm using https-proxy-agent sometimes it can be connected or not, can we add retry mechanism for http provider so every errors will be retried? currently I'm using p-retry in charge.

const web3 = new Web3(
  new Web3.providers.HttpProvider("https://bsc-dataseed1.binance.org:443", {
    agent: {
      https: HttpsProxyAgent(
        "http://auth@host:port"
      ),
    },
  })
);

web3.eth.net
  .isListening()
  .then(() => console.log("Provider is connected")) // sometimes binance accept the proxy IP
  .catch((err) => console.log("Wow. Something went wrong: " + err)); // sometimes not

My country internet is currently ban the provider. So proxy did help me.

Implementation Ideas

I would prefer in Web3.providers.HttpProvider options.

With web3 1.x, we can use fetch-retry to wrap global fetch, but with 4.x it's not possible out of the box. It would be nice if we could provide the fetch implementation to HttpProvider or have it contain something like fetch-retry.
