Description Pierre Prinetti 2020-08-19 10:29:43 UTC 
Description of problem:

Bootkube process loops endlessly to create the worker machineset due to the availability zone name having uppercase letters.

How reproducible: 100%

Steps to Reproduce:

1. Use availability zone name in install-config having at least one capital letter.
2. Run the create cluster command.


Actual results:
```
Aug 19 09:57:13 yus-pt67t-bootstrap bootkube.sh[2565]: [#12247] failed to create some manifests:
Aug 19 09:57:13 yus-pt67t-bootstrap bootkube.sh[2565]: "99_openshift-cluster-api_worker-machineset-0.yaml": failed to create machinesets.v1beta1.machine.openshift.io/yus-pt67t-worker-PowerKVM -n openshift-machine-api: MachineSet.machine.openshift.io "yus-pt67t-worker-PowerKVM" is invalid: metadata.name: Invalid value: "yus-pt67t-worker-PowerKVM": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')
