Ability to convert from one API version schema to another

[bryantbiggs]

Use case

Given a manifest, convert the manifest to the next, stable API version. Some resources only need the API version changed, others will require the schema to be modified to match the new API version

Solution/User Experience

Users should be able to provide a command, either on a per-file basis, or across a directory of files (recursive), searching for the deprecated API version and updating to the next stable version including any schema changes required (where applicable if a mapping is possible)

Possible command(s):

eksup migrate apiextensions.k8s.io/v1beta1 --dir . --recursive
eksup migrate apiextensions.k8s.io/v1beta1 --file manifest.yaml
eksup migrate apiextensions.k8s.io/v1beta1 --dir manifests --recursive --dry-run
