Checkbox to assign OOB on IP address creation

[llamafilm]

Since Netbox now has the ability to assign OOB IP address to a device (thanks to #13013), I think it would be helpful to add a checkbox for this when adding a new IP address, in the same way you can assign the Primary IP. I propose adding the checkbox right below this one, labeled "Make this the Out-of-band IP for the device"

As it is now, I have to first create the IP address and assign to the interface, then go to the device edit page and set it as Out-of-band IP here:

This would be a huge time-saver for us. I'd love to be able to mass-edit a bunch of IP addresses and mark them as OOB rather than individually editing a bunch of devices.
