Matej Ferencevic 53c405c699 Throw exceptions on RPC failure and Distributed error handling ... Summary: This diff changes the RPC layer to directly return `TResponse` to the user when issuing a `Call<...>` RPC call. The call throws an exception on failure (instead of the previous return `nullopt`). All servers (network, RPC and distributed) are set to have explicit `Shutdown` methods so that a controlled shutdown can always be performed. The object destructors now have `CHECK`s to enforce that the `AwaitShutdown` methods were called. The distributed memgraph is changed that none of the binaries (master/workers) crash when there is a communication failure. Instead, the whole cluster starts a graceful shutdown when a persistent communication error is detected. Transient errors are allowed during execution. The transaction that errored out will be aborted on the whole cluster. The cluster state is managed using a new Heartbeat RPC call.
