Patch kustomize for GPUs to provision in regions without zones on Azure

[bdattoma]

In order to support provisioning of GPUs in some regions of Azure where availability zone are not present we need to skip removal of "zone" key

Notes:

• it is forcing the replicas to 1 because in case there are no zones, the machine set will get created with n > 1 nodes
• atm among the regions we use, west us is the only one without zones

PR validation (on local CI):

1. provision in westus region: PASS
2. regression: provision in eastus2 region: PASS

Don't have thorough knowledge here, but seems good.

Don't like those missing new-lines warnings, though 😁

for some reasons adding a new line in my local branch of the file, doesn't mark the files as changed wrt remote branch..I tried to fix the new line error but I prefer not spending more time on it now. let's see if the warning disappears after the last sync I did
