feat: report the licenses a BMC asks for as facts (0.5.0)

get_licenses (napalm-device-types LicenseMixin, 4.15) on redfish and bmc,
for NetOrk/netork#1111.

- A BMC that refuses Redfish altogether reports each license it names as
  missing, with its message.
- One that answers but withholds parts reports the license with withholds,
  e.g. DCMS withholding drives and the firmware inventory on an X10 with
  only SFT-OOB-LIC.
- ipmi knows no licenses.

get_device_warnings keeps its two codes until netOrk derives them.
