Bolt-cli: Add dry-run flag for developmental/testing

[0ex-d]

Improvements:

• Add -d, --dry-run flag for bolt-cli: When provided commands will "simulate" actual behavior, for instance when making RPC calls or executing smart contracts without broadcasting on net.
• Spin Anvil instance for use cases like testing (we can get rid of explicit declaration in test):
  

  bolt/bolt-cli/src/commands/validators.rs

  Lines 165 to 171 in 6342fb2

  	async fn test_register_validators() {
  	let _ = tracing_subscriber::fmt::try_init();
  	let rpc_url = "https://holesky.drpc.org";
  	let anvil = Anvil::default().fork(rpc_url).spawn();
  	let anvil_url = Url::parse(&anvil.endpoint()).expect("valid URL");
  	let provider = ProviderBuilder::new().on_http(anvil_url.clone());

Closes #416

N.B: CI would fail, still figuring out somethings out:

• Do we necessary need to fork for subcommands with status (they do eth_call).
• If dry-run is needed for preconfs e.g bolt send.

Suggestion would be great here guys

This is great, thank you @0ex-d!

Ideally dry-run should be available only for commands that send a transaction on-chain (that benefit from simulation).

Here are the onchain commands we'd like to simulate:

• bolt validators register
• bolt operators eigenlayer deposit
• bolt operators eigenlayer register
• bolt operators eigenlayer deregister
• bolt operators eigenlayer update-rpc
• bolt operators symbiotic register
• bolt operators symbiotic deregister
• bolt operators symbiotic update-rpc

We can skip "bolt send" for now as it's for a slightly different use case!

No broadcast:

anvil --fork-url https://rpc-holesky.bolt.chainbound.io/rpc

forge script script/holesky/admin/Deploy.s.sol --rpc-url http://localhost:8545 --private-key {your_key} -vvvv --force

[merklefruit]

Thank you for this @0ex-d! We'll test it and review soon!

[0ex-d]

The tests can still be improved IMO, currently running them with dry_run: true because to indeed run a test, params should be more flexible for various scenerios like wallet balance.

Let me know if I got this right: you need this function (or more generally to manually drop anvil) and call it at the end of a command otherwise the compilers insert the drop too early, right after handle_rpc_dry_run is called because it is no more used.

[0ex-d]

Yes, that's correct.

Hey @0ex-d sorry for the delay, we will pick this up shortly! In the meanwhile, could you rebase this? We can't push anything to this branch

[0ex-d]

Sorry guys, being away, will jump on this now.

Closing in favor of #756
