Add sleep to reduce logging output

[ttwd80]

Description

The command kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}' is executed in a loop. When I run vagrant up the my screen is filled with:

    stack: ++ kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}'
    stack: ++ tr ' ' ,
    stack: + trusted_proxies=
    stack: + '[' '' '!=' '' ']'
    stack: ++ kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}'
    stack: ++ tr ' ' ,
    stack: + trusted_proxies=
    stack: + '[' '' '!=' '' ']'
    stack: ++ kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}'
    stack: ++ tr ' ' ,
    stack: + trusted_proxies=
    stack: + '[' '' '!=' '' ']'

Why is this needed

To reduce the verbosity.

How Has This Been Tested?

Tested on my on machine. It worked before the change. It worked after the change with less output.

    stack: + local loadbalancer_ip=192.168.56.5
    stack: + trusted_proxies=
    stack: + '[' '' '!=' '' ']'
    stack: ++ kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}'
    stack: ++ tr ' ' ,
    stack: + trusted_proxies=
    stack: + sleep 5
    stack: + '[' '' '!=' '' ']'
    stack: ++ kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}'
    stack: ++ tr ' ' ,
    stack: + trusted_proxies=
    stack: + sleep 5
    stack: + '[' '' '!=' '' ']'
    stack: ++ tr ' ' ,
    stack: ++ kubectl get nodes -o 'jsonpath={.items[*].spec.podCIDR}'
    stack: + trusted_proxies=10.42.0.0/24
    stack: + sleep 5
    stack: + '[' 10.42.0.0/24 '!=' '' ']'
    stack: + helm install tink-stack oci://ghcr.io/tinkerbell/charts/stack --version 0.4.5 --create-namespace --namespace tink-system --wait --set 'smee.trustedProxies={10.42.0.0/24}' --set 'hegel.trustedProxies={10.42.0.0/24}' --set stack.kubev

How are existing users impacted? What migration steps/scripts do we need?
