Region is not set correctly when demo cluster is choosen

[umut-saribiyik88]

Hi

If I try to create a demo cluster It always fails because the following line can not extract the zone correctly.
The variable "GCLOUD_ZONE" is empty.

fusion-cloud-native/setup_f5_gke.sh

Line 380 in 6d9cbe0

GCLOUD_ZONE=$(gcloud compute zones list --filter=region:${GCLOUD_REGION} | grep -m1 "${GCLOUD_REGION}-[a-z]" | cut -d' ' -f 1 | tail -1)

Especially the last part fails: cut -d' ' -f 1 | tail -1

Can you please check this?

Greetings
