Build Update for ovsrobot/ovs

Build: #2578
Status: Failed

Duration: 1 hr, 2 mins, and 30 secs

Message: ovs-ctl: Don't set hostname as external-id

ovs-ctl started to add the hostname as external-id [0] at some point.

However, this can be problematic as if it's already set by an external
entity it will get overwritten. In RHEL systems, systemd will invoke
ovs-ctl to start OVS and that will overwrite it to the hostname of the
machine.

For OVN this can have a big impact because if, for whatever reason the
hostname changes and the host gets restarted, ovn-controller won't
claim the ports back leaving the workloads unaccessible.

Also, it makes sense to leave this untouched as 1) it's an external_id,
so it will actually let external entities to configure it (unlike now),
and 2) it's optional. In the case of OVN, if the external-id doesn't
exist, it'll default to its hostname so nothing should get broken by
this change.
