> Refactor ECKeyOutputStream to make the code cleaner.
> Reuse code when writing the last stripe or rewriting failed stripes.
> The changes includes:
>  # handleDataWrite() has been changed to handleWrite(),
> it will check strip full and call encodeAndWriteParityCells().
>  # checkAndWriteParityCells() has been changed to encodeAndWriteParityCells(),
> and it can be reused to encode partial stripe in close().
>  # handleParityWrites() has seperated generateParityCells(),
> it can be reused in rewriteStripeToNewBlockGroup().
>  # handleFailedStreams() has been changed to excludePipelineAndFailedDN(),
> it will exclude both failed pipeline and failed datanodes.
>  # Reuse handleOutputStreamWrite() in close()
