You can build variables dynamically through hostvars, which is a hash of
all variables, host by host:
{{ hostvars[inventory_hostname]["ansible_" + main_nic].ipv4.address }}
inventory_hostname is the name of the current host in the host loop.
(Nesting templates in templates definitely will not work)
