[Numan Siddique]

Pass the dhcp options and extra dhcp options to the OVN in the Logical_Port.options field.
These values will be used by the ovn controller to support dhcp responder.

    Support native OVN DHCPv4

    OVN has added a new DHC_Options table in OVN NB DB to define
    DHCP options. Logical Switch ports refer to this table if
    DHCP is to be enabled.

    This patch creates rows for DHCP_Options for each of the
    subnets and adds the reference to the ports when created.

    If extra DHCP options are defined for a port, a new
    DHCP_Options row is created for the port.

    Fix delete subnet without DHCP enabled

    When using OVN native DHCP support, deleting a subnet without DHCP
    enabled will result in delete_subnet_postcommit failing. Since this
    failure is post commit to the neutron DB, the subnet is deleted from
    neutron. This patch set fixes delete_subnet_postcommit to handle
    subnets without DHCP options.

    Deployment fixes for DHCP and metadata support

    OVN native L3 and DHCP don't provide metadata support so config drive
    must be used when both are enabled. However, if the conventional DHCP
    agent is enabled it can be configured to provide metadata support.

    This patch set provides the necessary DevStack and Vagrant deployment
    fixes to properly configure DHCP and metadata support. In addition,
    documentation and release notes have been updated accordingly. And
    finally, the q-meta service was removed from devstackgatekuryrrc,
    since the gate job is setup for OVN native services.

    Fail deployment if q-dhcp and OVN_NATIVE_DHCP enabled

    Fail deployment if both q-dhcp and OVN_NATIVE_DHCP are enabled. Such
    deployments introduce unnecessary neutron DHCP provisioning blocks
