    Make AuroraThriftClient a synchronized singleton & Reconnect with Aurora scheduler on leader rotation

    This PR contains the following code changes to the "aurora-client" cloud module:
    
    1. The AuroraThriftClient.java singleton class has been made synchronized to handle race conditions. 
    2. If any call to aurora scheduler fails due to SocketTimeoutException, then it might be due to the fact that the Aurora scheduler leader has been re-elected (or rotated); In this case, the client will reconnect with current leader and re-execute the failed command.
    3. Added several sanity checks to detect malformed scheduler host URL, or detect if none of the scheduler hosts are reachable.
