add macvlan as a supported network driver
instead of using the --macvlan to indicate that you want to make a macvlan network, podman network create now honors the driver name of *macvlan*. Any options to macvlan, like the parent device, should be specified as a -o option. For example, -o parent=eth0. the --macvlan option was marked as deprecated in the man page but is still supported for the duration of 3.0. Signed-off-by: baude <bbaude@redhat.com>
