DCMI: Add get/set Configuration Parameters command
1.Systemd-networkd doesn't allow to configure DHCP timings, so set is
not implemented.
2.Get command to DHCP timings will return hardcoded values from
systemd-networkd source code.
3.Systemd-networkd doesn't support Random Back off, so not implemented.
4.As the info about VendorClassIdentifier is not clear in the spec,
Right now we are not supporting DHCP Option 60 and Option 43. We will
open new issue for it.
Resolves openbmc/openbmc#2752
