Can "profiles" get a "kind" field, too?

[ThinkOpenly]

Is your feature request related to a problem? Please describe.
I wrote a short Python script to read in all of the YAML files in the project for the purposes of verifying content, like what extensions are referenced, but never defined. The specific YAML files that reference extensions are (at least) instructions, extensions, CSRs, and profiles. The first three have a "kind" field identifying what each YAML represents, but the latter, "profiles", does not. Current "kind" fields are:

$ find . -name '*.yaml' -exec grep 'kind:' {} \; | sort -u
kind: certificate class
kind: certificate model
kind: csr
kind: extension
kind: instruction

Describe the solution you'd like
I'd like to see the YAML files describing profiles also have a kind field like:

kind: profile

Describe alternatives you've considered
It's actually difficult to work around, because the top-level field is a profile name, so not a consistent key that can be checked for existence.

Yes, that's the plan. The only reason it isn't done now is because @dlweaver is working on RVA23; I didn't want to interfere with the schema until he is ready.

If all it takes is adding a "kind: profile" field to RVB23 and RVA23, I can do that right away. Just let me know. (RVB23 is mostly done; probably won't start on RVA23 until early next week)
