Azure rotates supported minor versions relatively frequently. AKS can be deployed using just "major.minor" version, but a much newer version of Azure-CLI is required to do so. So, in order to not have to create a new config for each patchlevel change, we need to look up the full version that best matches the "major.minor" version we configure.
