> This JIRA is to use {{BlockInfo[] blocks}} for both striped and contiguous blocks in
INodeFile.
> Currently {{FileWithStripedBlocksFeature}} keeps separate list for striped blocks, and
the methods there duplicate with those in INodeFile, and current code need to judge {{isStriped}}
then do different things. Also if file is striped, the {{blocks}} in INodeFile occupy a reference
memory space.
> These are not necessary, and we can use the same {{blocks}} to make code more clear.
> I keep {{FileWithStripedBlocksFeature}} as empty for follow use: I will file a new JIRA
to move {{dataBlockNum}} and {{parityBlockNum}} from *BlockInfoStriped* to INodeFile, since
ideally they are the same for all striped blocks in a file, and store them in block will waste
NN memory.
