------------------------------

Hi [~drankye], per our discussion, Wei Zhou would help with this task. But I can't re-assign
the JIRA. Please feel free to assign it to Wei if you can edit.

> According to design, {{ErasureCoder}} is responsible to encode/decode a block group.
Currently however, we directly use {{RawErasureCoder}} to do the work, e.g. in {{DFSStripedOutputStream}}.
This task attempts to encapsulate {{RawErasureCoder}} to comply with the design.
