Review ipc-cli gas parameters

[raulk]

Akave folks have pointed out that ipc-cli transactions against Filecoin mainnet (e.g. subnet creation, subnet join, fund) seem to remain queued for long. This could be due to us miscalculating gas parameters (concretely the gas fee cap or premium). Even though we calculate our values based on the data returned by the Eth RPC API, it's possible that our code is carrying Ethereum assumptions that work for Calibrationnet (due to it being mostly vacant), but not for Mainnet.

I would maybe start here:

ipc/ipc/provider/src/manager/evm/manager.rs

Line 1283 in 9b4df00

pub(crate) async fn call_with_premium_estimation<B, D, M>(

And here:

ipc/ipc/provider/src/manager/evm/manager.rs

Lines 1332 to 1342 in 9b4df00

	fn base_fee_surged(base_fee_per_gas: U256) -> U256 {
	if base_fee_per_gas <= U256::from(40_000_000_000u64) {
	base_fee_per_gas * 2
	} else if base_fee_per_gas <= U256::from(100_000_000_000u64) {
	base_fee_per_gas * 16 / 10
	} else if base_fee_per_gas <= U256::from(200_000_000_000u64) {
	base_fee_per_gas * 14 / 10
	} else {
	base_fee_per_gas * 12 / 10
	}
	}
