Build Update for blp/ovs-reviews

Build: #398
Status: Failed
Duration: 37 minutes and 15 seconds
Commit: 7f66b55 (monitor_cond)
Author: Liran Schour
Message: OVN: Implementation of conditional monitoring usage
Conditional monitor of: Port_Binding, Logical_Flow, Multicast_Group
MAC_Binding tables. As a result ovn-controller will be notified only about
records belongs to a datapath that is being served by this hypervisor.
Performance evaluation:
OVN is the main candidate for conditional monitoring usage. It is clear that
conditional monitoring reduces computation on the ovn-controller (client) side
due to the reduced size of flow tables and update messages. Performance
evaluation shows up to 75% computation reduction.
However, performance evaluation shows also a reduction in computation on the SB
ovsdb-server side proportional to the degree that each logical network is
spread over physical hosts in the DC. Evaluation shows that in a realistic
scenarios there is a computation reduction also in the server side.
Evaluation on simulated environment of 50 hosts and 1000 logical ports shows
the following results (cycles #):
