Add QoS minimum egress bandwidth rule into ovs-agent
Add minimum egress bandwidth support for Open vSwitch. The scope of this implementation is reduced to N/S traffic. There is no QoS applied on traffic between VMs. The QoS rules are aplied to exit ports in bridges other than br-int; that means all physical bridges. No tunneled traffic will be shaped. This feature will be implemented in a following patch. Partial-Bug: #1560963 Change-Id: I0a2ef52b13151a39e678e9a3e6f75babb47298d0
