Small tweaks to catalog

[alasarr]

[x] 1. Return slug at every object with slug. For example, Dataset.slug doesn't work but it appears at dataset.to_dict. We talked about removing slug for the model but I'm regretting it after I've played a little bit with the library.

[x] 2. Dataset.to_dict(): remove summary_jsonb.

[x] 3. Rename Catalog to CatalogDataset

[ ] 4. Custom __repr__ for Variable objet.

That would be great to include only for Variable object the description fields at the repr.

For longer description (bigger than 20 characters let's add an ellipsis.

<Variable('CRMCYPERC_1a97ab94', 'My cool short description')>
<Variable('CRMCYPERC_1a97ab94', 'My cool long description bla bla bla ...' )>

I finally added the slug property at #1093 since I needed it for the CatalogList.get(slug) to work :)

2. Dataset.to_dict(): remove summary_jsonb.

I assume we want that for all entities with a summary_jsonb field (like Variable or Geography), don't we @alasarr ?

Yes, but only for to_dict the property should be available for describe

3. Rename Catalog to CatalogDataset

I think this will be included as part of #1018 . Should we handle it now or wait for that issue? @alrocar @oleurud

As for know I'd do what @alasarr requests, since these changes may affect directly the demo notebook and he's the owner of it.

Perfect, I'll change it here then 👍

<Variable('CRMCYPERC_1a97ab94', 'My cool short description')>
<Variable('CRMCYPERC_1a97ab94', 'My cool long description bla bla bla ...' )>

Maybe we should make it for longer than 30 characters or so (even the string 'My cool short description" exceeds the 20 characters limit).
