Launching instance with volume created from snapshot doesn't honor original image min_disk

[Beth Elwell]

When launching from Horizon an instance with volume creation from an image with a min-disk parameter :

* the volume size (GB) is automatically set to the minimum size
* if I choose a volume size inferior to this minimum size I get an error message: "The Volume size must be at least xxGB).

However, when trying to launch an instance with instance snapshot, the behaviour is much less user friendly:

* the Volume Size (GB) field is not automatically filled in with the minimum size
* the error message is not displayed before you click on the Launch Instance button

    Add same launch instance error handling as image to instance

    Previously, when launching an instance with an instance snapshot rather
    than with an image, the error handling was not as pleasant. I.e. the
    volume size was not automatically set to the minimum size and the error
    message would only appear after attempting to launch an instance. This
    is a small patch that addresses this and makes the user experience more
    friendly.
