feat: add ManagementControllerDriver for server BMCs

A role base for baseboard management controllers (Supermicro, Dell
iDRAC, HPE iLO, Lenovo XCC), reached over Redfish or IPMI, not SSH.

It declares, under TYPE_CHECKING only: get_power_state, set_power_state
(Redfish ResetType actions), get_hardware_inventory (CPUs, DIMMs,
drives, PSUs, NICs, and the server's serial, system UUID and NIC MACs),
get_event_log, get_firmware_inventory and get_management_protocols.

reboot_host restarts the BMC itself (Manager.Reset), never the managed
server, which goes through set_power_state. No HealthMetricsMixin and no
command channel; sensors come through NAPALM's get_environment.
