Cannot convert the value of type "System.String" to type "System.Security.SecureString".

[101-webapp-managed-mysql](https://raw.githubusercontent.com/azure/azure-quickstart-templates/master/101-webapp-managed-mysql/azuredeploy.json)

### Issue Details

I'm trying to use this template with the following code (so far):

`New-AzureRmResourceGroupDeployment -Verbose -Force -Name $appName -siteName $siteName -administratorLogin $dbUser -administratorLoginPassword $dbPass -ResourceGroupName $resGrp -TemplateUri https://raw.githubusercontent.com/azure/azure-quickstart-templates/master/101-webapp-managed-mysql/azuredeploy.json`

Here's the problem - with the parameter administratorLoginPassword - if I pass a string I'm told the string cannot be converted to securestring. That makes complete sense! So - I pass in a securestring and I'm told:

> ValidateLength attribute cannot be applied to a parameter that is not a string or string[] parameter. Make the parameter a string or string[] parameter.

So where I am right now is:

If I pass a string - I'm told it needs to be a securestring.
If I pass a securestring - I'm told it needs to be a string.

I'm obviously missing something here - can anyone help? 👍

Start with the 101-webapp-managed-mysql/azuredeploy.json template and the New-AzureRmResourceGroupDeployment command shown in the issue. Check how administratorLoginPassword is declared and passed through the deployment; done means the template and command agree on the accepted password type and the reported validation errors no longer occur.
