Support for updating page file setting in Azure environments

When you create a catalog in Azure environment, you can now specify the page file setting, including the location and size, explicitly using the  PoSH command. This will override the value determined by MCS. You can do this by running New-ProvScheme command and including the following custom properties:

• PageFileDiskDriveLetter: Page file location disk drive letter
• InitialPageFileSizeInMB: Initial page file size in MB
• MaxPageFileSizeInMB: Maximum page file size in MB
