    [FAB-12919] Serialize `SendSubmit` invocation. · 50af08bd
    Jay Guo authored
    This CR adds a mutex to guard parallel access to `SendSubmit`
    rpc call in etcdraft chain, due to thread-unsafe of gRPC.
    This is going to be tested by subsequent benchmark tests.
    Without this serialization, loading etcdraft orderer with
    many parallel requests would most likely cause a dead-lock
    in communication, which causes benchmark test to stuck.
