Improve kola argument processing logic for platform specific options

[travier]

Feature Request

If a platform specific option is passed to kola, it should default to that platform. For example if --aws-ami but the platform is not set, kola should default to the aws platform.

Example from (now removed):

coreos-assembler/mantle/cmd/kola/options.go

Line 180 in 0a09bd7

// TODO: Could also auto-synchronize if e.g. --aws-ami is passed
