CRD: ManagedOSVersion

[mudler]

Part of #58

Create the following new CRDs and controller for the resources types described below

ManagedOSVersion

ManagedOSVersion indicates the system version we want to upgrade to and that can be used within ManagedOS

apiVersion: rancheros.cattle.io/v1
kind: ManagedOSVersion
spec:
  version: <X>
  # or, if specified by any channel, a custom upgrade containerSpec
  upgradeContainerSpec: ...
  tags: [ "", "" ]
  minVersion: ""
  metadata: 
      <map[string]interface{}>
    CVEs: [" "] 
    Changelog: |....

The ManagedOSVersion declares its compatibility versions (range from which it can be upgraded to, and optional sets of constraints) and have to accomodate extra data (CVEs, Changelogs, etc ) this information have to be used purely from UI/UX interface, so we can treat them as metadata, but to keep in mind that has to be parsed programmatically somehow.
