==== Enhanced etcd backup and restore documentation

The etcd disaster recovery documentation was updated and simplified for quicker recovery of the cluster, both in a normal disaster recovery situation and in cases where a full cluster restoration from a previous backup is not necessary.

Two scripts, `quorum-restore.sh` and `cluster-restore.sh`, are introduced to complete many of the steps in the recovery procedure.

In addition, a procedure was added to more quickly recover the cluster when at least one good node exists. If any of the surviving nodes meets specific criteria, you can use it to run the recovery.

For more information, see xref:../backup_and_restore/control_plane_backup_and_restore/disaster_recovery/about-disaster-recovery.adoc#about-dr[About disaster recovery].
