sam boyer 07e5f8117f Reconcile coremodels, entities, objects under new kind framework (#56492)
* Update thema to latest

* Deal with s/Library/*Runtime/

* Commit new, working results of codegen

* We like pointers now

* Always take runtime arg for NewBase()

* Sketchy handwavy pass at entity meta framework

* Little nibbles

* Update pkg/framework/coremodel/entityframework.cue

Co-authored-by: Artur Wierzbicki <wierzbicki.artur.94@gmail.com>

* Move file into new framework location

* Introduce loaders, Go code

* Complete rename to kind

* Flesh out framework, add svg/dashboard examples

* Cruft removal

* Remove generated kind go files from gitignore

* Refine maturity concept, add SlotKind

* Update embed and go deps

* Export PrefixWithGrafanaCUE

* Make the loader actually work, holy crap

* Many small tweaks to type.cue

* Add Apache 2 licensing exceptions for kinds

* Add new kinds dir, start of generator

* Roll back to earlier oapi-codegen

* Introduce new grafana-specific CUE loaders

* Introduce new tidy code generators framework

* Catch up kind framework with tinkering

* Add slices for the generators

* Add write/verify step to main generator

* Many renames

* Split up kind framework cue files

* Use kind.Decl within generated kinds

* Create kind.SomeDecl wrapper type to cache lineages

* Better names again

* Get one generated implemented, hopefully

* Copy dashboard schema into new kind.cue

* Small fixes to make the initial gen work

* Put svg kind in its new home

* Add generated Go dashboard type

* More renames and cleanups

* Add base kind registry and generator

* Stop blacklisting *_gen.go files

This is not the Go best practice, anyway. All we actually want to ignore
for enterprise is generated wire files.

* Change codegen output directories

pkg/kind -> pkg/kinds
pkg/registry/kindreg -> pkg/registry/corekind

* Rename pkg/framework/kind to pkg/kindsys

* Add core structured kind generator

* Add plural and machine names to kind spec

* Copy playlist over to kind system

* Consolidate kindsys files

* Add raw kind generator

* Update CODEOWNERS for kind framework

* Touch up comments a bit

* More docs tweaks

* Remove generated types to reduce noise for review

* Split each generator into its own file

* Rename Slot kind to Composable kind

* Add handwavy types for customkind loading

* Guard against init calls to framework loader

* First pass at doc on extending the kind system

* Improve attribute example in docs

* Fix wire imports

* Add basic TS types generator

* Fix composable kind category def

* No need for a separate file with generate directive

* Catch dashboard schema up

* Rename generator types to something saner and generic

* Make version configurable in ts/go generators

* Add CommonMeta to ease property access

* Add kindsys prop indicating whether lineage is group

* Put all kind categories back in a single file

* Finish with kindsys group props

* Refactor maturity progression per discussion

- Replace "committed" with "merged"
- All kindcats can use all maturity levels, at least for now

* Convert ts veneer index generator to modular system

* Move over to new jennywrites framework

* Strip down old coremodel generator

* Use public version of jennywrites

* Pull latest thema

* Commit generated Go types

* Add header injection postprocessor

* Move sdboyer/jennywrites to grafana/codejen

* Tweak header output

* Remove dashboard and playlist coremodels

* Fix up backend dashboards devenv test

* Fix TS import patterns to new gen filename

* Update internal imports, remove coremodel registry

* Fix compilation errors, wire generation

* Export and replace the prefix dropper

* More Go struct and field name changes

* Last name fixes, hopefully

* Fix lint errors

* Last lint error
