Versioning and env valueFrom does not work in generators

[lingwooc]

If you do this with a versioned secret:

  components:
    echo-server:
      <other config>
      env:
        KAPITAN_SECRET:
          secretKeyRef:
            key: 'kapitan_secret'

You would expect the name found to include the version, but its taking its information from a bit of the dataset that doesn't yet have versions (they haven't been calculated yet).

A solution could be something like this (in WorkloadCommon):

    def update_env_for_versions(self, objects):
        for object in objects.root:
            rendered_name = object.root.metadata.name

            containers = self.root.spec.template.spec.containers
            for container in containers:
                for env in container.env:
                    if "valueFrom" in env and "secretKeyRef" in env["valueFrom"]:
                        if env["valueFrom"].secretKeyRef.name == rendered_name.rsplit('-', 1)[0]:
                            env["valueFrom"].secretKeyRef.name = rendered_name

called after
workload.add_volumes_for_objects(secrets)
I can't help but feel theres a neater solution, this could do unexpected things. It also only does secrets.

Applogies for the lack of PR, my generator is hacked about quite a bit in ways you wouldn't want and I'm pushed for time. I'll try and backport the other bits that are globally applicable and do a PR for this if no one can see a better solution.

The env["valueFrom"] pains me, but python insisted...
