Function domain_total_issuance_storage_key

pub fn domain_total_issuance_storage_key() -> StorageKey

Total issuance storage key for Domains.

This function should ideally use a Host function to fetch the storage key from the domain runtime. But since the Host function is not available at Genesis, we have to assume the storage keys. TODO: once the chain is launched in mainnet, we should use the Host function for all domain instances.
