linuxbridge scenario job fails with: "AttributeError: 'LinuxbridgeAgentExtensionAPI' object has no attribute 'request_int_br'"

[Ihar Hrachyshka]

log extension is not compatible with linuxbridge agent. We should, short term, avoid configuring it there; and long term, make it compatible with the agent. (It should be doable because the agent uses the same iptables firewall).

    Configure log extension for ovs scenario job only

    Current implementation of the agent l2 extension is not compatible with
    linuxbridge. More work should happen before it's possible to enable it
    back.

    log-api: Don't enable logging for linuxbridge

    We still run API tests agains logging API and the job has OVS enabled.
    As all linuxbridge flavors contain same string, this patch changes when
    logging service plugin is configured which is always but in linuxbridge
    scenario job.
