    SAMZA-1121: StreamAppender should not propagate exceptions to the caller

    StreamAppender#append currently propagates any exceptions while sending 
messages to the underlying logging system to the calling code. Since users 
don't expect log statements to throw exceptions, this can cause unexpected 
failures scenarios. We should catch exceptions and log to stderr instead.
