    Attachment: HDFS-11138-HDFS-7240.005.patch

Upload v005 patch to address [~anu]'s comments.

Fixing comments 3, 4 and 6 rely on changing the data structure in {{VolumeDescriptor}}, which,
as discussed, will be revisited later. The rest are fixed in v005 patch.

> This JIRA adds the skeleton for server side code, which is one of the core components
in block storage. For performance concerns, the server does not handle any actual read/write
operation but serving primarily as a meta data server. It provides four APIs:
> # create volume : which will call into underlying container layer to allocate containers
> # delete volume : delete a specific volume (as well as its containers)
> # info volume : return information of a specific volume
> # list volume : list all volumes
> Note that this is still subject to potentially major changes. Features such as persistence
are missing.
