This is a rather big change in jsonrpsee, the major things in this bump are: - Server backpressure (the subscription impls are modified to deal with that) - Allow custom error types / return types (remove jsonrpsee::core::Error and jsonrpee::core::CallError) - Bug fixes (graceful shutdown in particular not used by substrate anyway) - Less dependencies for the clients in particular - Return type requires Clone in method call responses - Moved to tokio channels - Async subscription API (not used in this PR) Major changes in this PR: - The subscriptions are now bounded and if subscription can't keep up with the server it is dropped - CLI: add parameter to configure the jsonrpc server bounded message buffer (default is 64) - Add our own subscription helper to deal with the unbounded streams in substrate The most important things in this PR to review is the added helpers functions in `substrate/client/rpc/src/utils.rs` and the rest is pretty much chore. Regarding the "bounded buffer limit" it may cause the server to handle the JSON-RPC calls slower than before. The message size limit is bounded by "--rpc-response-size" thus "by default 10MB * 64 = 640MB" but the subscription message size is not covered by this limit and could be capped as well. Hopefully the last release prior to 1.0, sorry in advance for a big PR Previous attempt: https://github.com/paritytech/substrate/pull/13992 Resolves https://github.com/paritytech/polkadot-sdk/issues/748, resolves https://github.com/paritytech/polkadot-sdk/issues/627
