bb06fa742a Render flux Kustomization along with api objects
This patch writes a Flux Kustomization to apply the api objects rendered
by a component instance.

190d0d2922 Normalize log messages
Make the log messages clear and readable, for example:

    holos render --log-format=json --log-level=debug \
      --cluster-name core2 ./docs/examples/platforms/reference/projects/secrets/components/namespaces/ \
      2> >(jq -r '"\(.source.file):\(.source.line)\t" + .msg')

The msg field is intended to have an imperative verb, ideally in the
past tense, followed by an actionable noun.  Past tense indicates
success where as the "could not foo: "+err error form indicates an
attempt to do something that failed.

18be35a0e4 Write component output for gitops
Write the result of the cue evaluation to a cluster specific path for
git ops.  The written file works with kubectl apply -f and a future
change will add the flux Kustomization and ArgoCD Application resources
to manage the same api objects using a gitops method.

e2b1fa0d47 Rename cue out field to content and add content-type
Content seems more appropriate of a field name, and it makes sense since
we are likely to output other formats than yaml, probably json too.  We
need to discriminate on content type, so also add a contentType field.

Semantics are meant to be the same has the http content type header, but
simple.

36193e4265 build kube api objects to stdout
This patch minimally wires up a basic cue based component to produce
rendered api objects on standard output.

```bash
(cd docs/examples && holos build ./platforms/reference/projects/secrets/components/namespaces)
```

```yaml
metadata:
  name: external-secrets
  labels:
    kubernetes.io/metadata.name: external-secrets
kind: Namespace
apiVersion: v1
```

776e90ee4d Add holos build subcommand using CUE Go API
This patch uses the CUE Go API to build a target directory.  The type of
thing being built is determined by first evaluating the `kind` field.

9bebd2e4b6 Discriminate on cue export type
Leaf directories can output different kinds of things:

 1. Platform specification.  A list of components to manage.
 2. Kubernetes API Objects suitable for kubectl apply -f- and friends.
 3. Helm values to provide to a helm chart to render API objects.

This patch adds an output schema and a kind discriminator so the holos
cli can figure out what type of output it's working with.  This makes it
possible to have a single `holos build <directory>` command that does
the right thing.
