* feat: upgrade react-select v1.3.0 to v3.1.0
Upgrade `react-select`, replace `react-virtualized-select` with a custom
solution implemented with `react-window`.
Future plans include deprecate `react-virtualized` used in other places, too.
Migrate all react-select related components to `src/Components/Select`.
* Fix new list view
* Fix tests
* Address PR comments
* Fix a flacky Cypress test
* Adjust styles for Select in CRUD ListView
* Fix loadOptions for owners select in chart PropertiesModal
TODO: add typing support for AsyncSelect props.
* Address PR comments; allow isMulti in SelectControl, too
* Clean up NaN in table filter values
* Fix flacky test
* [WiP] improve load_examples
related to #7472, longer term we will generate the examples by exporting
them into tarball as in #7472. In the meantime, we need this subset of
the features:
* allowing specifying an alternate database connection for examples
* allowing a --only-metadata flag to `load_examples` to load only
dashboard and chart definitions, no actual data is loaded
* Improve logging
* Rename data->examples
* Load only if not exist
* By default do not load, add a force flag
* fix build
* set published to true
