Failed to provision openstack port with os_port due to missing network param

[Dannyb48]

Describe the bug
Trying to provision a port on an openstack network using the os_port module fails with an error like

"Network is required"

I get the error even though I do specify name:

resource_group_type: openstack
resource_definitions:
   - role: os_port
     network: test_private_network
credentials:
  filename: clouds.yaml
  profile: openstack

According to ansible os_port module doc network name is required but linchpin is not setting that parameter.

To Reproduce
Steps to reproduce the behavior:

1. Define a pinfil with a resource_definition for role os_port
2. run linchpin -vvvv up
3. See error

Expected behavior
A port on an openstack network is successfully provisioned.
