        Path to Notebook Server Root Directories - Can be a Physical Location or Network Share Address
    .PARAMETER ServerDirectories
        Default Server Directories Object.
    .PARAMETER ConfigStoreCloudStorageConnectionString
        Connection string to Azure Cloud Storage Account to configure a Site with config store using a Cloud Store
    .PARAMETER ConfigStoreCloudStorageAccountName
        Account Name of the Azure Cloud Storage Account to configure a Site with config store using a Cloud Store
    .PARAMETER ConfigStoreCloudStorageConnectionSecret
        Connection string Secret to Azure Cloud Storage Account to configure a Site with config store using a Cloud Store
    .PARAMETER SiteAdministrator
