This adds a new 'baremetal dump <hostname>' command that outputs
the deployment playbook for a given baremetal node to the console.
The command reuses the playbook generation logic from BaremetalDeploy
including NetBox integration for local_context_data, netplan_parameters,
and frr_parameters.

Usage:
  osism baremetal dump <hostname>
  osism manage baremetal dump <hostname>
