@harikrishna-patnala This is reverted because of the lack of test report,
not the logic of your code. If you feel it must go in anyway please rebase the
code and make a new PR, make sure you add test instruction to up the chance
reviewers actually test.

> Key: CLOUDSTACK-9094
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9094
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server, Virtual Router
> Affects Versions: 4.6.0
> Reporter: Harikrishna Patnala
> Assignee: Harikrishna Patnala
> Fix For: 4.7.0
>
>
> From the logs we can see that the management server is sending the
> networkusagecommand to a VR twice within a very short interval. This doesn't
> have any impact on the network usage being reported, however it seems to
> consume direct agent threads unnecessarily.
> See the below snippet from the logs where networkusage command was sent to
> the same VR at the same time
