This update fixes the following bugs among others:
* A flaw was found in golang: crypto/elliptic, in which P-224 keys as
generated could return incorrect inputs, which reduced the strength of the
cryptography. The greatest threat to the system was confidentiality and
integrity. (BZ#1918750)
* This update adds new capabilities to the Baremetal Operator, allowing for
different reboot modes to be utilized. This allows workloads to be
relocated as quickly as possible in the event of a node failure.
Additionally, it provides a path for clients to quickly power down systems
for remediation purposes and to recover workloads. As a result, workload
recovery time is significantly reduced. (BZ#1936407)
