Add `airflow` to `DeviceType` model

[austind]

As ...

Austin - Network Automation Engineer

I want ...

To document a DeviceType's airflow direction, similar (or identical) to Netbox.

So that ...

As we add DeviceTypes, we can more clearly differentiate between SKUs that are otherwise identical (e.g., many NVIDIA/Mellanox SKUs). We can also filter/sort by airflow.

I know this is done when...

airflow is an attribute of the DeviceType model
