ClusterOutput attributes `enabledNamespaces` and `protected` are undocumented

[christopher-demarco]

Describe the bug:

ClusterOutput.spec.enabledNamespaces is completely undocumented:

• The CRD contains no description.
• The docs site does not contain that string except in the rendered CRDs, with no commentary.
• The codebase itself contains no comments.

ClusterOutput.spec.protected is not adequately documented:

• The CRD contains no description.
• The codebase contains no comments, although it is possible to determine its function by reading the code.
• The docs site only mentions the attribute in a "What's New" announcement.

Moreover, it appears that enabledNamespaces is not even used by the operator; I could only find it being declared in the CRD/schema specs. If it is truly unused, it should be removed from the CRD.

Expected behaviour:

The CRD should ship with descriptions of what the attributes actually do.

The documentation should include descriptions of what the attributes actually do.

Non-function attributes should either be noted as such, or removed.

Steps to reproduce the bug:

N/A

Additional context:

My use case for noticing this was that I'm hoping to find a way to constrain access on a ClusterFlow to only a subset of Flows; the names of these attributes suggest that they might be applicable.

Environment details:

N/A

We can delete enabledNamespaces as it is obsolete now and add some notes about the protected flag here:
