getOrCreatePort: add support to configure port Profile

Configuring port profiles can be useful to enable an application
running on the specified host to pass and receive VIF port-specific
information to the plugin.

One of the use-cases here is when configuring ports in OVS Hardware
offload, where we need to use the profile:
{"capabilities": ["switchdev"]}

Thanks to this patch, we'll now able to do it when creating the
machines and their ports.
