Anvil should gracefully deal with the upstream fork rate limits

[miohtama]

Component

Anvil

Describe the feature you would like

Currently, when using Anvil with quicknode.com hard fork Anvil may crash:

stderr: thread 'main' panicked at 'Failed to get fork block number: JsonRpcClientError(SerdeJson { err: Error("unknown field `code, expected one of id, jsonrpc, result, error, params, method`", line: 1, column: 7), text: "{\"code\":-32007,\"message\":\"100/second request limit reached - reduce calls per second or upgrade your account at quicknode.com\"}" })', /home/runner/work/foundry/foundry/anvil/src/config.rs:816:30

Additional context

This could be dealt with

• Anvil allowing to set the rate limit to the upstream, e.g. by a command line option --force-rate-limit 100/s
• Correctly throttle on Quicknode.com error if should throttling logic already exists in Anvil, instead of panic

@miohtama there was a PR merged with quicknode retry improvements, can you check if panic is still reproducible with latest anvil? thank you

@grandizzy this issue is outdated and can be closed, added test for good measure
