Add a function to build volume images

[Kuanlin-Chen]

Add function New-VolumeImage to build volume images, the volume image can be used as a D disk on Openstack instances.

How to use:

Set-IniFileValue -Path (Resolve-Path $ConfigFilePath) -Section "DEFAULT" `
                                                      -Key "image_path" `
                                                      -Value "C:\CloudImage\40G-D-Volume.img"
Set-IniFileValue -Path (Resolve-Path $ConfigFilePath) -Section "DEFAULT" `
                                                      -Key "image_type" `
                                                      -Value "MAAS"
Set-IniFileValue -Path (Resolve-Path $ConfigFilePath) -Section "vm" `
                                                      -Key "disk_size" `
                                                      -Value "42949672960"
New-VolumeImage -ConfigFilePath $ConfigFilePath

Excuse me, do you have any plan to promote this feature? If not, it's ok to close this thread.

Hello, thank you for the PR. Is there any reason you would like to have a volume image? Maybe dual boot or rescue images?

[Kuanlin-Chen]

It was for our VDI (Virtual Desktop) project which runs on OpenStack platform, customers required a particular volume size like 50GB, 200GB, or even 1TB, the volume will be attached to the Nova instances and works as a D drive on Windows OS.

My purpose was to generate volume images fast and automatically, but I can barely remember the reason why I did this through windows-openstack-imaging-tools rather than using OpenStack cli command, perhaps, we just tried to avoid increasing too much load for OpenStack.
