101-vm-secure-password does not reference keyvault

Regarding azure-quickstart-templates/tree/master/101-vm-secure-password, this template does not reference a key vault.

[Template Name goes here](Template link goes here)

### Issue Details
This template is described as "This template allows you to deploy a simple Windows VM by retrieving the password that is stored in a Key Vault. Therefore the password is never put in plain text in the template parameter file."

However, neither the current version of the template nor the parameters file references a keyvault. It appears that the keyvault was (inadvertently) removed at commit #ffe854534869c876df07d60b78fcd70fc02f877a (pr #7230).

As it stands, the template appears to deploy a standard VM and does not demonstrate the template use case.

Inspect the 101-vm-secure-password template and its parameters file, then compare them with commit ffe854534869c876df07d60b78fcd70fc02f877a and pull request 7230. Done means the template again references a Key Vault and retrieves the VM password as described, rather than deploying a standard VM without that use case.
