ci-automation/vms: handle platform names and generate the image formats

The kola test scripts are named by the platforms. The image naming is
also quite difficult to know and remember, e.g., whether "ami" or
"ami_vmdk" is needed for AWS tests and whether it's "vmware" or
"vmware_ova".

To address these problems the vms build stage now accepts the platform
names as format input, and for each platform it will automatically
generate the needed image types to run the tests.
