Maxime Beauchemin 3d08266714 [load_examples] download data at runtime (#7314)
* [load_examples] download data at runtime

When running `superset load_examples` to load example data sets,
Superset used to load from the local package. This created a few issues
notably around licensing (what are these datasets licensed as?) and
around package size.

For now, I moved the data sets here:
https://github.com/apache-superset/examples-data

Altered the logic to download the data from where it is stored.
