Add support to disallow rpc api endpoints

[mattsse]

Component

Anvil

Describe the feature you would like

anvil's api is quite massive and some endpoints are considered "god mode"

there are usecases where these should be restricted.

this should be done on the rpc server level because this is how the server is exposed and the easiest solution here is:

1. introduce a blacklist (HashSet of string) of certain endpoints in the config:

   foundry/crates/anvil/server/src/config.rs

   Line 8 in e215f3f

   pub struct ServerConfig {

2. if at least 1 blacklisted method, install another layer, similar to

   foundry/crates/anvil/server/src/lib.rs

   Lines 76 to 78 in e215f3f

   	if no_request_size_limit {
   	router = router.layer(DefaultBodyLimit::disable());
   	}

this layer should deserialize the request and reject disallowed methods, this is likely slightly inefficient but this deserialization overhead should be fine because we only need to check for method.

Hi, I would like to give this one a try

[grandizzy]

related #8731

[teodorstupnicki]

@mattsse I have 2 questions:

1. What do you think about this usage and command line format:

anvil --blacklist eth_sendTransaction,eth_sendRawTransaction

or is this one better:

anvil --blacklist eth_sendTransaction --blacklist eth_sendRawTransaction

2. What should be the expected response for a blacklisted method call - just a regular "Method not found"?

[mattsse]

yeah method not found or method not whitelisted

I'd also like to support some presets, like unsafe or something that by makes cli usage easier

@mattsse Could you elaborate on that? Maybe provide an example

[grandizzy]

just to simplify tracking, going to dupe it in favor of #8731 which is the same request
