Create etcd backup

This SOP should be followed in the following scenarios:

Resources

Connect to the os-control01 node associated with the ENV.
Use the oc tool to make a debug connection to a controlplane node
```
oc debug node/<node_name>
```
Chroot to the /host directory on the containers filesystem
```
sh-4.2# chroot /host
```
Run the cluster-backup.sh script and pass in the location to save the backup to
```
sh-4.4# /usr/local/bin/cluster-backup.sh /home/core/assets/backup
```
Chown the backup files to be owned by user core and group core
```
chown -R core:core /home/core/assets/backup
```
From the admin machine, see inventory group: ocp-ci-management, become the Openshift service account, see the inventory hostvars for the host identified in the previous step and note the ocp_service_account variable.
```
ssh <host>
sudo su - <ocp_service_account>
```

Copy the files down to the os-control01 machine.

scp -i <ssh_key> core@<node_name>:/home/core/assets/backup/* ocp_backups/
