need to do dscp/dot1p marking of control packets sent out of contrail components

[Vedamurthy Joshi]

Today, for instance XMPP packets have dscp marking just like any other ping packet from agent. (i.e. DSCP 0)

Since, they need to be treated with higher priority, like a typical network control packet..they should be for ex: 111000

Same should happen for other components as well. For ex: control node, discover/publish/subscribe messages etc. Let me know if they need to be tracked through separate bugs

Not targeted for R3.1

[Ashish Ranjan (aranjan-n)]

No need to RN this. Its day 1 behavior

Changes to slap DSCP bits on IP header of control packets.

Parse DSCP configuration in global-qos-config and use the value for
slapping DSCP bits on XMPP and DNS packets. The slapping of DSCP
bits are achieved by setting socket options on the sockets used for XMPP
and DNS communication.
