#11672

Add a flag to disable read tx timeout for long running APIs like debug_executionWitness, eth_getProof, etc

LGTM, but would also appreciate @mattsse or @joshieDo review, I don't have full confidence that these places are the only ones where we need to pass this argument to.

Let's tackle it via introducing an argument --db.transaction-timeout that can either set the custom timeout via --db.transaction-timeout 10s, or disable it fully via --db.transaction-timeout off.

We already have the logic for custom timeout, so we just need to set it using the CLI argument

	/// Set the maximum duration of a read transaction.
	pub const fn with_max_read_transaction_duration(
	mut self,
	max_read_transaction_duration: Option<MaxReadTransactionDuration>,
	) -> Self {
	self.max_read_transaction_duration = max_read_transaction_duration;
	self
	}
