* Add GetHostInterfaces command to redfish_info

Adding a GetHostInterfaces command to redfish_info in order to report the
following:
- Properties about the HostInterface(s) like Status, InterfaceEnabled, etc
- ManagerEthernetInterface (info on BMC -> host NIC)
- HostEthernetInterfaces (list of NICs for host -> BMC connectivity)

fixes #3692

* add fragment

* fixup for linter

* redfish_utils.py cleanup

- Remove unneeded Properties list from get_nic_inventory()
- Remove bogus key variable from get_hostinterfaces()
- Add additional Properties to collect from HostInterface objects

* fixup for stray deletion
