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.
bmc (napalm_redfish.bmc:BmcDriver) reads a BMC over Redfish where it
answers. A BMC that refuses Redfish (no license) is read and switched over
IPMI. A getter that fails over Redfish is asked over IPMI where IPMI has it;
IPMI is opened only then. Power control goes over Redfish when it answers,
and a refusal is final. The BMC is reset over Redfish only. Same account
for both; ipmi_port in optional_args.
Discovery suggests bmc for a BMC it finds: the fingerprint rules moved from
RedfishDriver to BmcDriver.
