Hi [~nandakumar131] rebased the patch on top of trunk.

> Eliminate the datanode ID file
> ------------------------------
>                 Key: HDDS-252
>                 URL: https://issues.apache.org/jira/browse/HDDS-252
>             Project: Hadoop Distributed Data Store
>          Issue Type: Improvement
>            Reporter: Bharat Viswanadham
>            Assignee: Bharat Viswanadham
>            Priority: Major
>             Fix For: 0.2.1
>         Attachments: HDDS-252.00.patch, HDDS-252.01.patch, HDDS-252.02.patch
> This Jira is to remove the datanodeID file. After ContainerIO  work (HDDS-48 branch)
is merged, we have a version file in each Volume which stores datanodeUuid and some additional
fields in that file.
> And also if this disk containing datanodeId path is removed, that DN will now be unusable
with current code.
