From the ovs doc, if mod-flow is used without --strict, priority is not used in matching. This will cause problem for downstream set_drop when duplicate_nic_upstream is disabled. For example: When set_drop is applied to upstream_nic_flow(#1), mod-flow will match both flow sonic-net#2 and flow sonic-net#3 as priority is not used in flow match. So let's enforce strict match for mod-flow. Signed-off-by: Longxiang Lyu <lolv@microsoft.com>

Approach
What is the motivation for this PR?
Improve the nic_simulator upstream nic traffic flow.
Currently, the upstream traffic from server nic is duplicated to both ToRs.
So the grpc traffic to the lower ToR could be forwarded to the upper ToR in such case, and those
traffic will go out the upper ToR via the default route though the port-channels. And those trivial traffic
will make some noises so some of the testcases that verify the port/queue counters will fail.

How did you do it?
Add two dedicated flows:
one to forward the traffic with upper ToR loopback IP to the upper ToR.
one to forward the traffic with lower ToR loopback IP to the lower ToR.
How did you verify/test it?
run
test_bgp_queuesand verify that the counters on tx queue 1 don't increase.Any platform specific information?
Supported testbed topology if it's a new test case?
