Flavors with zero disk size should not be disabled

[Ying Zuo]

Steps to reproduce:

1. Create a flavor with zero root disk

2. Create an image with minimum disk size as 10GB

3. Try to launch an instance from the image created in step 2 from either the Angular launch instance modal or the Python launch instance modal. You will get a help message indicating the flavor created in step 1 is not a valid option because it doesn't meet the minimum disk size set in the image.

The user won't be able to launch an instance with the zero disk flavor with either Angular or Python launch instance modal. According to the openstack guide[1], zero is a special case which uses the image size for the instance. Thus flavors with zero disk size should not be disabled because of the image disk requirement.
