OSD-26287 - Add '--reason' to 'osdctl cluster etcd-health-check'

[tnierman]

https://issues.redhat.com/browse/OSD-26287

---

Adds a required --reason flag to the osdctl cluster etcd-health-check command, allowing it to successfully exec into an etcd pod to run etcdctl commands.

For example, the current logic results in the following:

[tnierman@tnierman-thinkpadp1gen5] >> ~/workspace/osdctl/dist/osdctl_linux_amd64_v1/osdctl cluster etcd-health-check $CLUSTERID -S
INFO[0000] Backplane URL retrieved via OCM environment: https://api.stage.backplane.openshift.com 
INFO[0000] No PagerDuty API Key configuration available. This will result in failure of `ocm-backplane login --pd <incident-id>` command. 
INFO[0001] Backplane URL retrieved via OCM environment: https://api.stage.backplane.openshift.com 
INFO[0001] No PagerDuty API Key configuration available. This will result in failure of `ocm-backplane login --pd <incident-id>` command.

Adding the reason flag allows this to execute successfully:
