SRIOV with OVN needs neutron dhcp agent

[Numan Siddique]

In the case of OVN, ovn-controller service responds to the DHCP requests from the VMs. But in the case of SRIOV VMs, ovn-controller won't be able to capture the traffic sent via sriov directly to the switch.

So neutron dhcp agent should be deployed for OVN - SRIOV deployments.

    OVN: Add env file to deploy SRIOV with OVN.

    This patch adds an environment file to enable sriov agent with OVN. It is expected to
    include the environment file - environments/services/neutron-ovn-sriov.yaml
    after including the main OVN environment file. The main OVN environment files
    (neutron-ovn-ha.yaml, neutron-ovn-dvr-ha.yaml) disables all the neutron agent
    services.

    ovn-controller service responds to the DHCP requests from the VMs.
    But in the case of SRIOV VMs, ovn-controller won't be able to capture the traffic sent
    via SRIOV directly to the switch. So neutron-ovn-sriov.yaml enables dhcp agent.
