This change adds a new data migration: migrate_to_hardware_types.
It works by walking through known classic drivers, detecting matching
hardware types and interfaces and updates nodes accordingly.
Nodes that cannot be updated (e.g. matching hardware type is not
enabled) are skipped. A new migration option reset_unsupported_interfaces
can be set to True to allow resetting optional interfaces to their
no-op versions.
The example implementation are provided for the community supported
IPMI and SNMP drivers, as well as for fake drivers based on them.
