@scenes-react: Epic follow-up issues & tasks

[torkelo]

Epic with followup tasks following the merging of https://github.com/grafana/scenes/pull/734

Fundamentals

• [x] Basic design doc outlining the the approach
• [x] Url sync for objects added and removed from scene graph after initial sync
• [x] Url sync for same scene across page routes
• [x] Transformations @oscarkilhed
• [x] Annotations & data layers (@mdvictor 🏃 https://github.com/grafana/scenes/pull/782)
• [x] Migration / interoperability @torkelo 🏃 https://github.com/grafana/scenes/pull/777

Caching

• [ ] Caching of data state (@torkelo 🏃 POC https://github.com/grafana/scenes/pull/788)
• [ ] Caching of viz panel state
• [ ] Caching of query variable state (that is not above page routes)

Components

• [x] CustomVariable POC
• [x] CustomVariable more props + test
• [ ] QueryVariable + test -- @mdvictor
• [ ] DataSourceVariable + test -- @mdvictor
• [ ] LocalValueVariable
• [ ] AdHocFiltersVariable
• [ ] GroupByVariable
• [x] VizPanel basics
• [ ] VizPanel missing props
• [x] VariableSelect
• [x] Rename VariableSelect to VariableControl (https://github.com/grafana/scenes/pull/778)

Components nice to have

• [ ] CSSGridVizLayout (not critical but helps for standard / common viz layouts & default responsive views)
• [ ] FlexVizLayout (not critical but helps for standard / common viz layouts & default responsive views)

Hooks

• [x] useSceneQueryRunner + tests
• [x] useVariableValues + tests
• [x] useTimeRange
• [x] useVariableValues should be generic (https://github.com/grafana/scenes/pull/778)
• [ ] useVariableValue hook + test (single value variant)
• [ ] useVariableQuery (if your not interested in using a variable as a variable but only the resulting value options)
• [x] useDataTransformer (https://github.com/grafana/scenes/pull/775)

Fix name conflicts

• [ ] VizPanel exists in both libs (one scene object other react component)
• [ ] CustomVariable exists in both libs

Docs

• [ ] Intro to @grafana/scenes-react
• [ ] Variable docs
• [ ] Visualization docs
• [ ] Using custom scene objects
• [ ] Migration

@axelavargas I removed the assignments, I think it should be clear that anyone can pick up tasks from this epic, just add your name to the task before (and maybe write about it in #wg-scenes)
