[hwsig] sushy-oem-idrac for Hardware Vendor SIG

Hi, I would like to propose moving sushy-oem-idrac [1] that is used in Ironic project to Hardware Vendor SIG. sushy-oem-idrac is iDRAC specific OEM extension of vendor-independent sushy [2] library and both use Redfish to communicate with BMCs. Any feedback welcome. Regards, Aija [1] https://opendev.org/x/sushy-oem-idrac/ [2] https://opendev.org/openstack/sushy Internal Use - Confidential
