This PR implements the `archive_unstable_storage` method that offers support for: - fetching values - fetching hashes - iterating over keys and values - iterating over keys and hashes - fetching merkle values from the trie-db A common component dedicated to RPC-V2 storage queries is created to bridge the gap between `chainHead/storage` and `archive/storage`. Query pagination is supported by `paginationStartKey`, similar to the old APIs. Similarly to the `chainHead/storage`, the `archive/storage` method accepts a maximum number of queried items. The design builds upon: https://github.com/paritytech/json-rpc-interface-spec/pull/94. Closes https://github.com/paritytech/polkadot-sdk/issues/1512. cc @paritytech/subxt-team --------- Signed-off-by: Alexandru Vasile <alexandru.vasile@parity.io> Co-authored-by: Niklas Adolfsson <niklasadolfsson1@gmail.com>
