    Remove wait_msgq from SandeshWriter since TcpSession Send already
    buffers the unsent data. This helps simplify the SandeshSession/
    SandeshWriter send code. SendInternal updates the ready_to_send
    flag based on the TcpSession Send. In WriteReady callback, set
    ready_to_send to true and kickstart the send queue processing.
