This resource is required to add more than a single router interface to
a neutron network or subnet. By default, using
`neutron_router_interface` to add a second router to a subnet without
first creating a port for it will cause IP conflicts.
This resource can be used to first retreive a non-conflicting ip on a
target network or subnet, then create a `neutron_router_interface` with
the port.
Eg:
```
neutron_router { $tenant:
tenant_name => $tenant,
gateway_network_name => 'public',
require => [
Neutron_network['private'],
Neutron_subnet[$private_subnet],
],
} ->
neutron_port { "${tenant}_private":
ensure => present,
network_name => 'private',
subnet_name => $private_subnet,
} ->
neutron_router_interface { "${tenant}:${private_subnet}":
ensure => present,
port => ${tenant}_private",
}
```
