Rework the --network parse logic to support multiple networks with specific network configuration settings. --network can now be set multiple times. For bridge network mode the following options have been added: - **alias=name**: Add network-scoped alias for the container. - **ip=IPv4**: Specify a static ipv4 address for this container. - **ip=IPv6**: Specify a static ipv6 address for this container. - **mac=MAC**: Specify a static mac address address for this container. - **interface_name**: Specify a name for the created network interface inside the container. So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99 for the default bridge network as well as for network names. This is better than using --ip because we can set the ip per network without any confusion which network the ip address should be assigned to. The --ip, --mac-address and --network-alias options are still supported but --ip or --mac-address can only be set when only one network is set. This limitation already existed previously. The ability to specify a custom network interface name is new Fixes #11534 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
