Edward Haas	a3cde17fc0	bridge: Add mac field to specify container iface mac Controlling the mac address of the interface (veth peer) in the container is useful for functionalities that depend on the mac address. Examples range from dynamic IP allocations based on an identifier (the mac) and up to firewall rules (e.g. no-mac-spoofing). Enforcing a mac address at an early stage and not through a chained plugin assures the configuration does not have wrong intermediate configuration. This is especially critical when a dynamic IP may be provided already in this period. But it also has implications for future abilities that may land on the bridge plugin, e.g. supporting no-mac-spoofing. The field name used (`mac`) fits with other plugins which control the mac address of the container interface. The mac address may be specified through the following methods: - CNI_ARGS - Args - RuntimeConfig [1] The list is ordered by priority, from lowest to higher. The higher priority method overrides any previous settings. (e.g. if the mac is specified in RuntimeConfig, it will override any specifications of the mac mentioned in CNI_ARGS or Args) [1] To use RuntimeConfig, the network configuration should include the `capabilities` field with `mac` specified (`"capabilities": {"mac": true}`).
