macvtap: agent starts although no interface_mapping is provided

[Andreas Scheuring]

As the macvtap agent does only support flat and vlan networks, the physical_interface_mappings prameter must contain at least one mapping. Without a mapping, no networkconnectivity can be provided by this agent.

Ideally the agent would terminate with an appropriate error message pointing the operator to this issue.

    Terminate macvtap agent when physical_interface_mapping config not present

    Starting the macvtap agent without specifying at least one
    physical_interface_mappings does not make sense. As it only
    supports layer2 networks (flat, vlan) an interface mapping is
    mandatory. An existing agent deployment without an interface
    mapping can not serve any networks to instances!

    This patch terminates the agent when no mapping is
    provided. As without this mapping the agent cannot serve any networks
    for instances, this patch can't really break existing deployments.

    UpgradeImpact Agent terminates when no physical_interface_mapping
    configuration is provided.
