tee-worker is blocked when create node_api if parachain don't start

[DogLi]

the WsRpcClient here include a RpcClient, and RpcClient impl Handle, the Handle includes a function on_error, it uses default on_error function which just print out the error log. So when the WsRpcClient call the function direct_rpc_request, it fist connect the server, when getting a fused error, just print out the error log, the connect function still returns Ok, the result_out.recv() in the direct_rpc_request will waiting forever.

need to test:

When node_api is created successfully(which means the parachain is ok), if the WebSocket disconnected, what will happen when we use node_api? will it block the whole program?

maybe some solutions:

1. How to re-establish the connection after listen event connection is lost? scs/substrate-api-client#246
2. use tungstenite-client feature
3. Software Design: Add reconnection possibility scs/substrate-api-client#382
