Allow --resolver option when getting VM's IP

[PRESIDENT810]

I'm using --network-bridged=en0 when to launch my VM, and according to cirruslabs/tart#472, I should use --resolver=arp to get VM's ip address, because the default dhcp doesn't work for bridged network.

However, this packer plugin seems not to be providing this option currently, and if I pass run_extra_args = ["--net-bridged=en0"] in the source block, packer build cannot find the VM's ip address correctly (because it's using dhcp resolver).

Is it possible to add a option to allow passing --resolver option to this plugin? Thanks!

We can probably add something like ip_extra_args.
