Bug Description

When running "contrail-status" command or clicked "WebUI" of sandesh_uve Introspect,
the following messages logged at /var/log/contrail/contrail-control.log
> 2015 Oct 07 18:58:56.277051 JunTsn00 [Compute:contrail-tor-agent:1:TCP][SYS_ERR] : TcpSessionMessageLog:6323 Session
> 127.0.0.1:9010::127.0.0.1:43181 < Read failed due to error 2 : End of file
But "contrail-status" was fine (All status of node were active).

And also, there are displayed logs at WebUI when using Contrail Version 2.21, in other side there aren't displayed logs at WebUI when using Contrail Version 2.20.

Customer would like to understand reasons why the logs were created when we used "contrail-status" and why the logs were displayed at WebUI by using Contrail Version 2.21 (in case of Version 2.20,there were not displayed logs at WebUI).

if we do contrail-status, then check contrail-logs --module contrail-vrouter-agent, we see these errors..

Dont log error in case of eof error for async_read

async_read returns eof to indicate that the other side has closed the socket.
This is a way for other side to know that socket should be closed now. There
is no need to log since it is not an error condition

Closes-Bug: 1506795
